A box 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 be cleaned with 3 boxes of this detergent

You start with multiplying the weight of one laundry detergent (5.2 oz) by 3:

5.2 * 3 + 15.6

Then you would divide the answer (15.6) by. 7 oz:

15.6 /.7 = 22.9

But the question is how many full loads so the answer is 22 full laundry loads.

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. (:

Answer: 22 full loads
