Abox of powdered laundry detergent contains 5.2 ounces of detergent. it takes 0.7 ounce of detergent to clean a load of laundry. how many full loads can by cleaned with 3 boxes of this detergent?

We know that there are 3 boxes of detergent that are all 5.2 oz.  To find out how many oz you have all together, you need to multiply 3 by 5.2    This comes out to 15.6
Now, you need to divide 15.6 by 0.7      This comes out to 22.2857143... and on and on, but it asks how many full loads can be cleaned. You can only do 22 full loads with three boxes of detergent. (:

22 full loads

Hope this helps, and feel free to ask more questions if you need!! (:
