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?
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.
