Visualizing Multiplication of Fraction Using Models

Front

What is a fraction?

Back

A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number). For example, 1/2 means one part out of two equal parts.

How do you multiply fractions?

Back

To multiply fractions, multiply the numerators together and the denominators together. For example, (1/2) * (2/3) = (1*2)/(2*3) = 2/6 = 1/3.

If Jenny has 7/8 of a tank of gas and uses 2/3 of it, how do you find out how much gas she used?

Back

Multiply 7/8 by 2/3. (7/8) * (2/3) = (7*2)/(8*3) = 14/24 = 7/12.

If Darwin has 1/2 meter of plastic and uses 1/5 of it, how do you calculate the part he used?

Back

Multiply 1/2 by 1/5. (1/2) * (1/5) = (1*1)/(2*5) = 1/10.
