[@jimbuchanan2026]

My only question about your answer is? 'Why did you leave it in an improper fraction?' I only ask because I was always taught to reduce, reduce, reduce, and never leave it as an improper fraction. Thus I would have ended with 3 7/12. Note the space between the 3 and the 7! I was taught that if a mixed number was in the question then try to end with the best reduced mixed number.

I was just about to comment that I like to reduce it even further to 3 and 7/12. I think it's better when reduced in this fashion, because in that form it's plain and obvious that you have 3 plus part of a whole. That's not clear from 43/12.

[@rogeraffleck8677]

Where did you go to school? I learned this nearly 70 years ago and 43/12 was a perfectly good answer. In fact it was preferred to the equivalent form 3 and 7/12 because it is much easier to work with. For example half of 43/12 is simply 43/24 but half of 3 and 7/12 requires multiple steps.

I did this in my head and changed the improper fractions to mixed numbers as I went along. For example, I dropped the 2 and added 3/4 to 5/6 using LCD getting 19/12 by adding 9/12 to 10/12, then subtracted 12 from 19 to get 7 which becomes the numerator at 7/12 plus the remaining 12/12 becoming 1-7/12. I then added that back to the 2 I dropped before for 3-7/12 or 43/12.

First thing is 1/2 x 5/3 which is 5/6, I’m pretty sure. Then you turn the mixed number into an improper fraction. And that is 11/4. And just speaking of improper fraction, I was taught to save simplifying for final step of problem solving. Then you take the improper fraction from the mixed number and add it to the 5/6. So you take 33/12, which is 11\4 with a common denominator of 12 and figure out the other fractions. Then you’re left with 33/12 + 5/6. LCD is 12. So then you’re left with 33/12 +

I may be wrong, but I started by calculating the 2 highest denominators 2 3/4 + 1/2 × 5/3 33/12 + 1/2 × 20/12 (then 1/2 of 20/12 which is 10/12) which makes 33/12 + 10/12 Which is 43/12 or 3 7/12 It's the way my brain works 😊

So, why stop when you almost find the correct answer? Divide 43 by 12 and you get 3 and 7/12. That's the final answer. But why go so long? I saw immediately that both 4 and 3 have 12 as first common multiplication factor. So you get 2 and 9/12 + (1/2 of 20/12). Half of 20/12 is 10/12. So you get 2 and 9/12 + 10/12.

Then you talked about converting improper and mixed fractions and drew arrows that appears to indicate that 3/2 is converted to 3 1/2 and vice-versa. For your "literal" watchers, (NO! Not Buffy's Watcher) maybe use 1 1/2 instead.

[@peggieincolfaxca3818]

I love it that you check your work. My grrandkids can do the math, but dont know how to check or even estimate the answers. (Kindergarten in 1947 -- but I STILL love to refresh my math knowledge. Thank you!)

[@renaeschuchard9824]

2 3/4 + 1/2 × 5/3 = 2 3/4 ( 1×5/2×3)= 2 3/4 + 5/6 = 11/4 + 5/6 = 33 +10 /12 = 43/12 =3 7/12

I wish you had been in my math class 76 years ago!!

Personally I try to avoid fractions. In the UK, like most of the world we use metric measurements so for the most part, fractions can be avoided. I simply convert this to 2.75+0.5x1.66

[@juergenilse3259]

The great disadvantage of not using fractions is, that you may get rounding errors. Some number (like 5/3 or 7/12 in this case) have no exact representation with a limited number of decimal places. So you have to use fractions to get the exact result in this case. Evenif you do not need the exact result or if you need the resullt in a decimal representation, it may be an advantage to keep the fractions as long as possible and only convert the final result to a decimal representation, because the rounding errors may be lower (you avoid rounding errors "on the way").

[@kanehunter23]

Every math teacher I have ever had wanted it as 3 7/12

[@timothyandrews2157]

I need to rest.🤯 I've learned more in the last 2 hours watching your videos than I tried to learn in high school.

[@suzyallen332]

I've got a headache 😢

[@rosmeartoo]

Due to the absense of parentheses to indicate the order of execution there are two answers. Therefore the problem is invalid (except to make this point). 65 or 59

[@gavindeane3670]

No parentheses are required here. Mathematical notation has grammar rules that make this expression unambiguous. Nothing wrong with adding parentheses for clarity if you want to though.

[@yudabuddha]

Can you make these shorter, please?

[@aivel3973]

If I were dealing in measurements with the 43 over 12 or 43/12 I would need to reduce it down. Or if I had a pie sale and there were 43 pieces left and someone wanted to buy the 43 pieces ai would need to know what to charge and it came to 3.58333333 which 3 + 1/2 pies + .083333/12 Is there anyway to write that as a fraction. I know how to get the money for the pies at 20 a pie. I would multiply 3.58333333 x $20 if I was a miser and wanted every penny for every crumb😂😂😂 But how would I write that as a fraction using mixed a number fraction?

[@joshuawayneyork]

I HATE adding and subtracting fractions! It's so much easier to multiply and divide.

[@anniew4893]

Yes..thank you

[@christinerice3726]

I enjoy your videos! More! More!

[@paparayg]

The final proper answer is 43 divided by 12 which equals 3 and 7 twelfths!

[@cyberthug62]

.5x1.666=.833+2.75=3.588

[@josephinetennassee3343]

Three whole number and seventh twelfths. I love to work Maths😊😊

[@dustinbingham7322]

3.5833333333333333333 real world correct answer.

[@flagmichael]

It is easy to get wrong only if one relies on PEMDAS rather than using parentheses in writing the equation. It is irresponsibly lazy not to use parentheses in this.

[@gavindeane3670]

Wouldn't be much use as a tool to teach the grammar rules then though, would it.

[@2040wagon]

Fun video to follow. I made many mistakes and would given a mixed fraction at the end which would not have been 3 7/12 because I would have been wrong along the way. 😢😅

[@mattblack9069]

Try giving a clear answer eg 43/12 =3 7/12

[@JoyceHynes-v1q]

And what type of a great job would it get you if you could solve that problem....hello

[@nunyafa]

What real life situation/occupation involves this math ?

[@marinecorpswarrior915]

Cooking and carpentry also if you are laying pipes

[@generalmanagerformays587]

First thing is order of operations

[@kurtjohnson4816]

Convert to decimal and get 3.58, same as 43/12

[@bsmith8564]

My head told me to add 2.75 + .5 x .6 is this not correct?

[@davidbosworth4751]

11/4 and 5/6 multiply 11x 6 and 5 x 4 so its 66/24 and 20/24 = 86/24

[@wilnerlouissaint644]

I think it's not finished. You could take 43÷13 to reduce it.

[@jfloyo11]

here is the easier way 2.75 + .5 * 1.666666666666 = 3.583333333333

[@patsavage1245]

Only America still likes fractions. Third world country.

[@tusk242]

Became lost. have to restart. IF this was on an exam, a lot of TIME used up, when no cal. are allowed.

[@robertbrauner3529]

Thanks!

[@danieldennis9831]

43/12 or 3 7/12

[@Nobody-ld7mk]

You just inspired me to get my TI 36 Pro out and arrive @ 43/12 or 3.58333333333333333333333>>>>>>

[@marlenearocho3680]

I wish I had had you for a math teacher. I didn't do well in high school and didn't graduate college cause I couldn't pass algebra. 😢

[@palemale2501]

I got 3 and 7/12ths in 15 seconds - a retired engineer who went to school over 50 years ago.

[@Sailor376also]

I got 3 7/12ths Carpenter,,, we have 12ths on our framing square.
