Question

The ratio of Evan’s red toy cars to blue toy cars is 3:4. Evan has 12 red toy cars. How many blue toy cars does Evan have?

Answer 1

Let the number of red toy cars be 3x
So the number of blue toy cars is 4x

Now
3x = 12

so, x = 4

Therefore number of blue toy cars is (4 × 4) = 16

So Evan has 16 blue toy cars.

Answer 2

Evan got total blue cars = 16

explaining..
3:4 by taking both as dominator it becomes

1/3 and 1/4

and now as we know the value of 1/3 = 12

common difference is = 4

so for making ratio of 3:4

we need to multiply both ratio with common diff.

3*4 = 12( given )
4*4 = 16 ( answer )
