What does nomerator mean?
Mispelling of 'numerator'. Numerator is the top half of a fraction. If you have x/y, then x is the numerator.
How do you solve for the numerator when the denominator and the answer are known?
Multiply the answer by the denominator.
How do you solve multplicative inverses to solve equations?
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.
Help with proportional fractions?
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.

How do you solve order of operations with fractions?
solve the top and bottom first, as if each were in parentheses. Then Divide the numerator by the denominator
