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 ?

To find the value of y when x is 15 units, we can plug in the values into the ratio x/3 = y/4:

15/3 = y/4

Simplifying the equation, we get:

5 = y/4

To solve for y, we can multiply both sides by 4:

4 * 5 = 4 * y
20 = y

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