The question I had a hard time with was #10 on 3-6 pg. 124. It’s 5 times 1/8. What I learned is that first when there is a whole number you have to put it into 5/1. So if The whole number was 3 you would put into 3/1. They you Would simply cross multiply. So you would multiply 5 times 1 and 1 times 8.

Example on pg. 124 #10

Cross multiply to find the answer

You use this in every day life. We can use it by Cutting pieces of pie. You want everyone to have a piece so u can use it like that. Another example is in drinks.

There are also story problems on the same page that explain how you can use it in real life too.
