1/4 + .8 + .3 can you add fractions and decimals? BE CAREFUL! Easy to make a mistake…

1.35 in about five seconds in my head. Nice one!

[@arnoldkellner2173]

I did it in less than 10 seconds. Of course I’m 76 years old and a math nerd. I can see math in my head. I get into trouble with my grand kids because I like to skip steps, showing your work was not how I learned to do math.🇺🇸🇺🇸🇺🇸👍😂

Great!

[@francoisefincoeur5371]

1/4= .25 + .80 + .30= 1.35 ?

[@stevenjohnson1143]

Simple convert the fraction to its decimal equivalent so .25 plus .8 1.05 plus .3 totaling 1.35

[@mitchbogart8094]

When choosing between converting to decimals or converting to fractions, especially given easy decimals to convert, fractions are better and maintain the infinitely precise, perfect answer. With decimals it could very easily come out inexact. If one immediately converts 0.8 to 4/5, you're practically done! You have some 4ths, 5ths, and 10ths as denominators. 4x5=20 is the obvious choice for the lowest common denominator, so you easily convert the fractions to 20ths, add to get 27/20 and in 10 seconds you're done. I think most people of all ages really remember their arithmetic. In any case, short videos like this one quickly refresh people's memory!

Read through comments. Agree with one stating to use leading zeros for decimal fraction representation. Solved for the 1.35 using ¼=0.25, then reduced the 0.35 to get mixed number 1 7/20, but forgot the fraction only solution of 27/20. Good video for learner's (other than the preceding 0 comment - which was drilled into us when told "show your work" - got deducted points for that representation. The reason being "the decimal may not always be visible (when quickly writing by hand) and the fraction cannot be mistakes." This, plus: "Never do math in ink; always use pencil." Semantics, petty stuff????

.25 + .8 +.3 = 1.35

[@Herlongian]

I would go 5/20+16/20+6/20= 27/20. If you are an arithmetic student, convert 27/20 to a mixed number for practice or a decimal number for practice. If you are an algebra student, you already know how to do that so you are done!

In all modesty I cannot conceive how you can make a 17 minute video to explain something that can be calculated in your head before the second advert starts...?

[@pseuda]

Dude, have you ever wondered there are people who are starting to learn fractions and decimals? These videos are super cool!

[@kathsch8966]

I agree. His videos are always way to long. He goes off on tangents sometimes. But over all good videos.

0.25 + 0.80 + 0.30 = 1.35

[@mustafaalshaikh1061]

1.35

[@contessa.adella]

0.25+0.8+0.3 takes about five seconds to add up in your head. Seeing the video, I don’t get why you’d be converting it all into fractions first. That’s just making work for nowt.

[@johngiorgi4000]

Sadly I think you are not teaching people correctly when using decimals. You should always use a zero before the decimal to avoid mistakes. So 0.8 instead of.8, etc. Anyway, the new way is just plain lazy. Someday this will be costly. I will give you a thumbs down.

[@enriqueiii9209]

27 ÷ 20 = 1 7/20, your students and others are going to get confuse, so explain how you would get .35.

[@windywednesday4166]

It's 1.35. The easiest way to do this is to convert 1/4 to 0.25 then just add up the numbers. To convert 7/20 to decimal place you multiply both the top and the Bottom by five to get 35/100...=.35 or 35%.
