So Isaiah has a total of 6 gallons of paint and each bookcases takes 1/3 gallon. How many bookcases can he paint?
Alright to solve this problem, we can simply take the total gallons of paint Isaiah has and divide that by 1/3
So 6 divided by 1/3 should give us the answer.
But how do we divide fractions? Remember this useful tip for all throughout your school life when you don't have a calculator: Keep, Change, Flip
Keep the first fraction, change the sign to a multiplication sign, and flip the second fraction.
This should give us 6 x 3/1 or 3, which is 18.
Isiah will be able to paint 18 bookcases.
Hope this helped!
