How do you find the total when one quantity is a multiple of another?

Back

To find the total when one quantity is a multiple of another, multiply the smaller quantity by the multiple. For example, if Tonya made 12 cookies and Sara made 4 times as many, calculate 12 x 4 = 48.

Front

What is the identity property of multiplication?

Back

The identity property of multiplication states that any number multiplied by 1 remains unchanged. For example, 8 x 1 = 8.

Front

What is the zero property of multiplication?

Back

Multiplication and division are inverse operations. If you multiply a number by another, you can find the original number by dividing the product by that number.

Front

How do you divide a length into equal parts?

Back

To divide a length into equal parts, divide the total length by the number of parts. For example, to divide 36 inches into 4 parts, calculate 36 ÷ 4 = 9 inches.

Front

What is a factor in multiplication?

Back

A factor is a number that is multiplied by another number to get a product. For example, in 4 x 5 = 20, both 4 and 5 are factors.
