Percentage-Decimal-Fraction Relations Calculator

40 is 80 percent (%) of what number?

Let's call our missing number x.
Expressing this in terms of an equation, we get 40 = 80% * x
Since a percentage is just the percent number divided by 100, we have:

40 =	80x
	100

Multiply both sides of the equation through by 100 and simplify:

40 * 100 =	80 * 100x
	100

4000 = 80x

Since we want to solve for our missing number x, divide each side of the equation by 80

Cancel both 80 and simplify:

x =	4000
	80

Therefore, our missing number x = 50
Now we know that 40 is 80 percent (%) of 50.
