Pooja writes the ratio x over 3 = y over 4 to help her increase the size of a two-dimensional shape. If the new value of x is 15 units, what will be the value of y ?

Answer 1

To find the value of y , we can set up a proportion using the given ratio:

x/3 = y/4

Substitute the value of x as 15 units:

15/3 = y/4
5 = y/4

Multiply both sides by 4 to solve for y :

4*5 = y
y = 20

Therefore, the value of y will be 20 units.
