Pooja writes the ratio x/3 = y/4 to help increse the size of a two-dimenstional shape. If the new value of x is 5 units. If the new value of x is 15 units, what will be the value of y?

To find the value of y when x is 15 units, we can use the ratio x/3 = y/4.

Plugging in the new value of x (15 units):
15/3 = y/4
5 = y/4
y = 20

Therefore, when x is 15 units, the value of y will be 20.
