How do you multiply a fraction by a whole number?

Back

To multiply a fraction by a whole number, multiply the numerator of the fraction by the whole number and keep the denominator the same. For example, 2 x 3/5 = (2 x 3)/5 = 6/5.

What does it mean to simplify a fraction?

Back

Simplifying a fraction means reducing it to its simplest form, where the numerator and denominator have no common factors other than 1.

What is an example of a visual model for multiplying fractions?

Back

A visual model can be a rectangle divided into equal parts. For example, if you have 1/2 of a rectangle and you want to find 3 times that, you can shade 3 sections of 1/2.

Front

How can you use a number line to multiply fractions?

Back

You can use a number line to show how many parts of a fraction fit into a whole. For example, to multiply 1/4 by 3, you can mark 1/4 three times on the number line.
