Let's call our missing number x. Expressing this in terms of an equation, we get 9 = 45% * x Since a percentage is just the percent number divided by 100, we have:
9 =
45x
100
Multiply both sides of the equation through by 100 and simplify:
9 * 100 =
45 * 100x
100
900 = 45x
Since we want to solve for our missing number x, divide each side of the equation by 45
900
45
=
45x
45
Cancel both 45 and simplify:
900
45
=
45x
45
x =
900
45
Therefore, our missing number x = 20 Now we know that 9 is 45 percent (%) of 20.
