You buy a family-size box of laundry detergent that contains 48 cups. If your washing machine calls for 1 and 1/5 cups per wash load, how many loads of wash can you do?

40 loads

Step-by-step explanation:

To find how many loads of wash you can do you need to divide 48 by 1 1/5.

There are two ways you can divide this, the first way is converting 48 to a fraction and dividing them.

48/1 divided by 1 1/5

convert 1 1/5 to an improper fraction

48/1 divided 6/5

change the division to multiplication and find the reciprocal of the second fraction.

48/1*5/6 = 240/6

Simplify to 40/1 or 40

The second way is changing 1 1/5 to a decimal, so its 1.2

Then divide 48 by 1.2 and you get 40.
