Pooja writes the ratio x/3 = y/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

Given ratio x/3 = y/4, we can cross multiply to find:

4x = 3y

Given that the new value of x is 15 units, we substitute x = 15 into the equation:

4(15) = 3y
60 = 3y
y = 20

Therefore, the value of y will be 20 units.
