Explains how multiplication can help you find 7+7+7.
To use the multiplication facts for 3 to help you find the multiplication facts for 9, you can utilize the concept of equivalent fractions. Here's how you can do it:
Step 1: Start by listing the multiplication facts for 3: 3 x 1 = 3, 3 x 2 = 6, 3 x 3 = 9, 3 x 4 = 12, and so on.
Step 2: Observe that the multiplication fact for 9 (which is 3 x 3) is already included in the multiplication facts for 3.
Step 3: Recognize that 9 can be written as the product of two fractions: 3/1 x 3/1. This means that 9 is equivalent to 3 multiplied by 3.
Step 4: Apply the concept of equivalent fractions to find the multiplication facts for 9. For example, 9 x 2 can be expressed as (3 x 3) x 2. Simplifying this expression, we get 3 x (3 x 2) = 3 x 6 = 18. So, the multiplication fact for 9 x 2 is 18.
Step 5: Continue this process for other multiplication facts for 9. For instance, 9 x 3 is equivalent to (3 x 3) x 3, which simplifies to 3 x (3 x 3) = 3 x 9 = 27. So, the multiplication fact for 9 x 3 is 27.
By using the multiplication facts for 3 and applying the concept of equivalent fractions, you can find the multiplication facts for 9 and extend this method to other multiples of 9.
