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 set up a proportion using the initial ratio provided by Pooja:
x/3 = y/4
Substitute x = 15 into the equation:
15/3 = y/4
5 = y/4
Cross multiply to solve for y:
5 * 4 = y
20 = y
Therefore, the value of y will be 20 units when the new value of x is 15 units.
