Pooja writes the ratio x/3=y/4 to help 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 when x is 15 units, you can set up a proportion based on the original ratio:

x/3 = y/4

Now plug in the new value for x:

15/3 = y/4

Now, simplify the left side of the equation:

5 = y/4

To solve for y, multiply both sides of the equation by 4:

4(5) = 4(y/4)
20 = y

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