10/13 = ?/78
78/?= 13 so ? = 6
10/13 x 6/6 = 60/78
You can also cross multiply 78x10/13=60, but if you have to use multiplying by one, use the above method.

How do you solve an equation where x is a numerator?
You would normally start by multiplying both sides of the equation by whatever is in the DENOMINATOR (the bottom part of the fraction), to get rid of fractions.
How do you solve all fractions problems?
You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.
How do you solve mixed numbers?
You can convert a mixed number to an improper fraction by multiplying the denominator by the whole number, adding the numerator and putting that total over the denominator. 2 and 3/4 = 4 x 2 + 3 = 11/4
How do you solve an equation with two equal signs?
An equation with two equal signs is really to explicit equations (or three implicit ones). For example, expession 1 = expression 2 = expression 3 is equivalent to expression 1 = expression 2 AND expression 2 = expression 3 and, by transitivity, expression 1 = expression 3 So you need to solve two of the above three.
How do you solve for the numerator when the denominator and the answer are known?
Multiply the answer by the denominator.
