Front

What is a fact family in mathematics?

Back

A fact family is a group of related addition and subtraction or multiplication and division equations that use the same numbers.

How do you identify the numbers in a multiplication and division fact family?

Back

In a multiplication and division fact family, you identify the numbers by finding the two factors that multiply to give a product and the corresponding division equations.

Front

What is the relationship between multiplication and division in a fact family?

Back

Multiplication and division are inverse operations; the product of two numbers can be divided by one of the factors to yield the other factor.

What is the product of 8 and 9?

Back

The product of 8 and 9 is 72.

Front

If you know one factor and the product, how can you find the missing factor?

Back

You can find the missing factor by dividing the product by the known factor.

Front

What is the missing factor if the product is 40 and one factor is 8?

Back

The missing factor is 5, since 8 multiplied by 5 equals 40.
