If you have 2 fractions then you do cross multiplication where you take the left numerator and times it by the right denominator if your looking for the numerator. If your looking for the denominator then you do the same thing only you use the top as your divider not the bottom. Well if it is an equation with another fraction equaling it, you can multiply the denominator by a number that will allow it to have the same value of the denominator in the other fraction. Once you know that number ( the one it took so the denominators were equal when multiplied) you just divide the fraction ( the one you have both denominator and numerator) by that number, and put it over the original lone denominator, then you have your answer. If you only have the numerator you use pretty much the same concept except opposite the steps. Here's an example: 7/? = 21/30 You would know 7 multiplies with 3 to get 21, so you divide 30 by 3 (the number it took to get 7 to be 21), and you get 10. Then you put the 10 underneath the original 7/? resulting in the answer being 7/10. So 7/10=21/30. Hope this is the answer you were looking for.
Well.. You see how many times the Denominator (Bottom Number) goes into the Numerator (Top Number) And add on the remainder to the Numerator. Lets say... 38 over 5 for example. 5 goes into 38 7 times (35) And has three left. So the answer as a mixed fraction would be 7 3/5
For ALL fractions ; Numerator(top) / denominator(bottom(. Hence 1 over 7 = 1/7 '1' is numerator and '7' is the denominator.
if it is 3/7, the numerator is 3 (top)
The numerator is 5.The denominator is 9.
The numerator for the answer to #7 is -36.
38/7
7 out of 38 is 18.42%

7/38 is in its simplest form.
38/7 x 7/38 = 1 = multiplicative inverse 38/7 + -38/7 = 0 = additive inverse
