Achef has 15 3/4 lb of beans. she packs them in freezer bags that weigh 2 1/4 lb each. how many freezer bags of beans does the chef pack?

You would need 7 freezer bags because you have to turn both fractions into improper fractions. to get that you have to multiply 15 by 4 and then add 3 so you get 63/1. Then for the next fraction, you multiply 4 by 2 and then add 1 so you get 9/1.

Now you have to divide the 2 fractions to find out how many freezer bags you need. So it would look like this. 63/1 divided by 9/1.
To divide fractions, you use the rule  (keep, change, flip) 
So you keep the first fraction 63/1 but you change to division sign to multiplication and lastly you flip the second fraction from 9/1 to 1/9 and now you multiply so it looks like this.

63/1 x 1/9 and you get 63/9 which equals 7 freezer bags. 

I hope this helped you?? :)
