If x is 125% of y, then y is what percent of x?
Let's solve this using algebra.
If x is 125% of y, we can write it as:
x = 1.25y
To find y as a percentage of x, we need to find the value of y in terms of x. Dividing both sides of the equation by 1.25, we get:
y = x/1.25
To express y as a percentage of x, we divide y by x and multiply by 100:
y/x * 100 = (x/1.25) / x * 100 = (x*100) / (1.25*x) = 100/1.25
Therefore, y is 80% of x.
