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

Answer:

Mark have left  $\frac{11}{28}$ gallon yellow paint,  $\frac{3}{8}$ gallon green paint and  $\frac{1}{8}$ gallon blue paint.

Step-by-step explanation:

Mark wants to paint a mural.

Mark has yellow paints =  $1\frac{1}{7}$ gallons

He has green paint =  $1\frac{1}{8}$ gallons

quantity of blue paint =  $\frac{7}{8}$ gallons

He plans to use  $\frac{3}{4}$ gallon of each paint.

after painting mural, amount of yellow paint left = $1\frac{1}{7}$ -  $\frac{3}{4}$ =  $\frac{32-21}{28}$ = $\frac{11}{28}$ gallon

Amount of green paint left =  $1\frac{1}{8}$ -  $\frac{3}{4}$ =  $\frac{9-6}{8}$ =  $\frac{3}{8}$ gallons

Amount of blue paint left =  $\frac{7}{8}$ -  $\frac{3}{4}$ =  $\frac{7-6}{8}$ = $\frac{1}{8}$ gallons

Mark have left  $\frac{11}{28}$ yellow paint,  $\frac{3}{8}$ of green paint and  $\frac{1}{8}$ of blue paint.

Total amount of paint left =  $\frac{11}{28}$ +  $\frac{3}{8}$ +  $\frac{1}{8}$ = $\frac{25}{28}$
