Calculate one-third times five-sevenths.

To multiply these two fractions together, the first step is to multiply the numerators. In this case, one times five. One times five is five. Our next step is to multiply the denominators together. Three times seven equals 21.

One-third times five-sevenths equals five over 21. But before we write that as our final answer, we ask the question, can we simplify or reduce this fraction? Can five twenty-firsts be written in a reduced form? No, five twenty-firsts cannot be reduced any further, which makes five over 21 our final answer.
