The strip below shows a sidewalk that is 2/3 of a mile long and is made up of 6 sections. How many sections make a sidewalk that is 1 mile long?

2/3 is 6sections so if we divide 2/3 by 6 we would find the length of one section.
(2/3)/6=2/18= 1/9
How many 1/9 is equal to 1?
If we multiply 1/9 by 9 we would get 1
So the answer is 9sections

This law is sometimes called the grouping property. as you can see, regardless of how the numbers are grouped, the answer is still 13. the associative law of multiplication is similar to the same law for addition. it says that no matter how you group numbers you are multiplying together, you will get the same answer.
