Question

Mark wants to paint a mural. He has 1 1/7 gallons of yellow paint, 1 1/8 gallons of green paint, and 7/8 gallon of blue paint. Mark plans to use 3/4 gallon of each paint color. How many gallons of paint will he have left after painting the mural? Enter your answer as a simplified fraction.

Answer 1

Amounts of paint left over are:

Yellow: 1 1/7 - 3/4 = 32/28 - 21/28 = 11/28 gallon

Green: 1 1/8 - 3/4 = 9/8 - 6/8 = 3/8 gallon

Blue: 7/8 - 3/4 = 7/8 - 6/8 = 1/8 gallon

Add 11/28 gallon, 3/8 gallon and 1/8 gallon to answer this question.

Answer 2

Mark have left
`(11)/(28)` gallon yellow paint,
`(3)/(8)` gallon green paint and
`(1)/(8)` gallon blue paint.

Explanation:

Mark wants to paint a mural.

Mark has yellow paints =
`1(1)/(7)` gallons

He has green paint =
`1(1)/(8)` gallons

quantity of blue paint =
`(7)/(8)` gallons

He plans to use
`(3)/(4)` gallon of each paint.

after painting mural, amount of yellow paint left =
`1(1)/(7)` -
`(3)/(4)` =
`(32-21)/(28)` =
`(11)/(28)` gallon

Amount of green paint left =
`1(1)/(8)` -
`(3)/(4)` =
`(9-6)/(8)` =
`(3)/(8)` gallons

Amount of blue paint left =
`(7)/(8)` -
`(3)/(4)` =
`(7-6)/(8)` =
`(1)/(8)` gallons

Mark have left
`(11)/(28)` yellow paint,
`(3)/(8)` of green paint and
`(1)/(8)` of blue paint.

Total amount of paint left =
`(11)/(28)` +
`(3)/(8)` +
`(1)/(8)` =
`(25)/(28)`
