Apaint store has 35 gallons of paint in storage, 2/5 of which are for outdoor use. the others are for indoor use. if each gallon costs $22, what is the total cost of indoor paint in storage?

You need 3/5 of the 35 gallons of paint, so all you need to do is divide 35 by 5 to get 7 and multiply that by 3 to get 21. 3/5 of 35 is 21. Then, if each gallon is $22, you just multiply 21x22 to get your cost.

1/5= 35 divided by 5= 7
3/5= 7x3=21

$22x21=$461 for 21 gallons of paint
