To cross multiply, multiply the denominator on the left by the numerator on the right. Then do the same for the denominator on the right and the numerator on the left. These new expressions will be equal to each other. For your example, it will look like: (x-9) (-2)= (x) (7) Distribute/multiply to get: -2x + 18 = 7x. Making The Denominators the Same. Multiply top and bottom of each fraction by the denominator of the other. This always works, but we often need to simplify the fraction afterwards, as in this example (press play button): We simplified the fraction 20 32 to 10 16 , then to 5 8 by dividing the top and bottom by 2 each time, and that is as simple ... 21 Sept 2023 ...
