If 5 is to 40 as x is to 16, what is the value of x =? Let’s Solve the Ratio problem step-by-step!

[@redblack8414]

The answer is 2. Can be done mentally in one second.

[@michto47]

2 secondes for me

[@redblack8414]

@@michto47 I didn't timed myself. Maybe it was 2 seconds.🙂

[@steveville54]

It took 5 seconds to solve it in my head. 😂

[@russelllomando8460]

got 2 simple ratio 5/40 = X/16 40X = 80 thanks for the fun.

[@dawnradel9008]

Figured it out without all the steps. My math teachers hated that I could do that.

It's a simple one, but I love the practice 🙂 Thanks for what you do, it's appreciated.

[@jenniferjohnson7279]

I am not a math wizard but....if 5 divided by 40 is " 8", then 16 divided by "8" is 2....i don't know if this a right formula but i ckd end of video and my answer was 100% correct...yay for little old me (literally)..

[@argonwheatbelly637]

2 in about two seconds in my head. Fun one!

[@Kleermaker1000]

You simply divide 40 by 5 = 8 and then 16 by 8. That gives 2. So X =2. Basic arithmetics.

[@JDMc2.0]

I used times tables in my head and figured it out in under 10 seconds.

[@KLeonardM]

Oh ffs, you made this confusing for most people. Simple math like this should be explained right away. You can make another video on the ratio percentage

[@tomtke7351]

5 v 40 x v 16 5/x = 40/16 x = (5)(16)/(40) = (5)(4)/(10) = (4)/(2) = 2

[@jessemallory741]

I use this concept a lot so this was a piece of cake-handy concept to know and understand

[@thomasharding1838]

X = 8. "5" = the sum of the digits of "40" +1, 4+0+1=5 so X will equal the sum of the digits of "16" +1, 1+6+1 = 8. Either that or 40/5 = 16/X => (40xX) = (5x16) => 40X = 80 => X = 2

[@gavindeane3670]

5 is an eighth of 40. What's an eighth of 16? 2 is.

[@ab_ab_c]

This is the simplest approach without even having to know what cross-multiplying is. I solved it the same way 5/40*16, which is 1/8*16, which is 16/8 which is 2.

[@mauriziograndi1750]

5*16/40 = 2 this was taught in the lower grades at school. The product of the medians is equal to the product of the extremes.

[@Geoff_G]

X/16 = 5/40 X = 5×16/40 X = 80/40 X = 2

[@krunoslavregvar477]

5:40=1:8=x:16 so it means x = 2 Also, we can/could put it in this way: 5/40=x/16 so 5*16=40x\\:40 x=80/40=2

[@martinemjt]

{5 times 16} divided by 40. x is 2

[@RenitaSeals]

The answer is 2. Set the problem up as a proportion-- one side equal to the other side( proportion).

[@robinsommerhauser-sz1jh]

Did it in my head..2 because that's how we were taught.

[@pulsar22]

Why should the statement " ... is to ..." mean ratio and proportion? Could it not be addition, subtraction ... or quadratic equation

[@dazartingstall6680]

5/40 = x/16 40x = 80 x = 2 Or 5 = 40 ×12.5% 16 × 12.5% = 2 ∴ x = 2 Or 5/40 = 1/8 = 2/16 If 2/16 = x/16 then x = 2

[@Janie-y6e]

I just did the final part (reducing) in my head and quickly got the 2 for x.

[@open_water2411]

Cross multiply and get the answer instantly.

[@open_water2411]

5*16/40 = 2

[@charlesmitchell5841]

X =2

[@DidiWaDidi]

I solved it in a split second without really knowing how. Your instructions were harder to understand than solving the problem. 😂

[@bigdog3628]

never learned this and wonder why I would ever need it.

[@dazartingstall6680]

This is literally how maps work.

[@michaelhoerig5920]

All this talk just to solve a very easy problem in Algebra? Cross-multiply. That's it! Simple!

[@williamjames305]

X = 2. (5 x 8 = 40) ====>> ("X" x 8 = 16) =====>> "X "= 2

Ratio and proportion

[@MrMousley]

5 is to 40 as X is to 16 5 is 1/8th of 40 40/5 = 8 So we need to work out 1/8th of 16 16/8 = 2 The answer is 2

[@chrisdissanayake6979]

5/40 = X/16 40X = 5x16 40X = 80 X = 2

5/40 same as 1/8 = x/16. -->x=2

x/16 = 5/40 = 1/8 = 2/16 and so x = 2
