When doing fractions, you may cross multiply.
How do you find missing fractions?

How do you multiply fractions with uncommon denominators?
To multiply fractions all you do is multiply the numerators and the denominators separately eg: 4/7 x 6/11 = 24/77. The "commonality" of denominators has no relevance.
How do you clear fractions?
I am not entirely sure what you mean with "clear". But if you want to get rid of fractions in an equation, you can multiply both sides of the equation by the least common multiple of the fractions. For example, take the equation: (1/2)x + 3 = (1/5)x If you multiply both sides by 10, you get: 5x + 30 = 2x
When do you cross multiply in dividing fractions?
To divide fractions, turn the second one over - that is, swap its numerator and denominator - and multiply. Nothing else is necessary. You cross multiply when you have a proportion, that is when you have two ratios that are equal.
