When multiplying fractions, remember to 'flip and multiply' – this means you must flip the second fraction and then multiply across both fractions. A fraction is a part of a whole. When dividing fractions, you must divide the numerators and denominators. One way to check your answer to a fraction problem is to multiply the fractions and then simplify the answer. The answer should be the same as the original problem.
