Out of 32 students in a class 5 said they ride their bikes to school based on these results predict how many of the 800 students in the school ride their bikes to school

Make a proportion.(an equation that shows that two ratios[in fraction form] are equal) If 5 out of 32 kids ride their bikes (5/32), what out of 800 ride their bikes(?/100)? 5/32 and ?/800 are the ratios in your proportion. It's going to be set up like this:

5 ? =
32 800

Now you you have to find the missing info (represented by the question mark) by cross multiplying. In order to do that, you can either 1. multiply 5 by 800 and divide that answer by 32 or 2. divide 5 by 32 (5÷32) and multiply that answer by 80. For questions like this, setting up proportions are the best way to go. Good Luck!

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.
