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, what will be the valeu of y

To find the value of y, we need to solve for y in the given ratio:

x/3 = y/4

Plugging in the new value of x (15):

15/3 = y/4
5 = y/4
y = 5 x 4
y = 20

Therefore, the value of y is 20.
