If you are given an equation that is missing a number, use your knowledge of multiplication and division facts to find the missing number. If the missing number is your product or quotient, then multiply or divide the given numbers as shown.If the missing number is one of the two being multiplied or divided, use the given quotient or product to help you find it.

You know that 9 multiplied by something will equal 18. To find that something, rethink the equation as 18 divided by 9 to find the missing piece.The same idea works in the other problem. If you know something divided by 8 equals 2, then rethink the equation as 8 multiplied by 2 equals that something.The video to the right offers further examples.
