Write the division sentence. For instance, you might have 5/6 / 2/5.
Flip the fraction being divided. This is known as creating the "reciprocal" of the original fraction. In this example, you would flip 2/5 to get 5/2.
Multiply the two fractions once the second fraction is in reciprocal form. Multiply the numerators (top numbers) together and the denominators (bottom numbers) together. In this case, you would multiply 5 and 5 to get 25 and 6 and 2 to get 12. This would give you 25/12.
Simplify the answer if necessary. In this case, you could simplify 25/12 to 2 1/12. This is because 12 will fit into 25 twice with 1 left over.
