Mispelling of 'numerator'. Numerator is the top half of a fraction. If you have x/y, then x is the numerator.
Multiply the answer by the denominator.
The multiplicative inverse, or reciprocal, of a number "x", is "1/x". For example, the multiplicative inverse of 5 is 1/5. For a fraction, just exchange numerator and denominator. For example, the multiplicative inverse of 2/5 is 5/2.
The important thing to know is the following. If you have an equality relating two fractions, for example:1/2 = 3/6,then the numerator of one fraction times the denominator of the second is the same as the numerator of the second times the denominator of the first. In this example, 1 x 6 = 2 x 3. This can often be used to solve problems. For example, a typical question with percentages is, "20 is 15% of...?" Writing this as a proportion, and remembering that percent means hundredths:20/x = 15/100Now just solve for x. 15x = 20 times 100, 15x = 2000, x = 166.67.The important thing to know is the following.

solve the top and bottom first, as if each were in parentheses. Then Divide the numerator by the denominator
