you need 2 gallons of paint to paint a mural. you already have 3/8 gallon yellow paint and 1/4 blue paint
You'll need more paint.
He needs 5 of the 1/8 gal of paint and 2 of the 1/4 gal of paint
To find out how much more paint you need, you'll need to add up the amounts of yellow and blue paint you already have, and then subtract that total from the 2 gallons required for the mural.
First, let's convert the fractions to a common denominator to make the addition easier. The common denominator for 8 and 4 is 8. So, let's convert 3/8 to a fraction with a denominator of 8:
3/8 = (3/8) * (2/2) = 6/16
Now, we can add up the yellow and blue paint in terms of the 1/16th gallon:
Yellow paint: 6/16 gallon
Blue paint: 4/16 gallon
To find the total amount of paint you have, add these two amounts:
6/16 + 4/16 = 10/16 gallon
Now, to find out how much more paint you need for the mural, subtract this total from the 2 gallons required:
2 - 10/16 = 32/16 - 10/16 = 22/16
Therefore, you still need 22/16 gallon of paint to complete the mural.
