FAQ

How is multiplying a fraction by a whole number the same as repeated addition?

Just as 3 × 4 means adding 4 three times, 3 × 1/4 means adding 1/4 three times to get 3/4 — connecting multiplication to its repeated-addition meaning makes the concept accessible.

What is the algorithmic method for multiplying a fraction by a whole number?

Multiply the whole number by the numerator and keep the denominator unchanged — for example, 4 × 3/5 = 12/5 — then convert to a mixed number if required.

Is multiplying fractions by whole numbers a 4th grade Common Core standard?

Yes — CCSS 4.NF.B.4 specifically addresses multiplying a fraction by a whole number, making it a key new fraction concept introduced in 4th grade.
