Best Answer

You can use algebra to find 40% of 20, since that's what I normally do.

Say 100x = 20, as in 100% = 20.

Here we divide both sides by 100, so x = 20/100 = 1/5

This means that 1% of 20 is equal to one fifth.

Then multiply both sides of the equation by 40, so 40x = 40/5 = 8.

Therefore 40% of 20 = 8.

20 = .40 of x

X = 20 / .4

x = 50, Thus 20 is 40% of 50.
