Answer:
Mark have left [tex]\frac{11}{28}[/tex] gallon yellow paint, [tex]\frac{3}{8}[/tex] gallon green paint and [tex]\frac{1}{8}[/tex] gallon blue paint.
Step-by-step explanation:
Mark wants to paint a mural.
Mark has yellow paints = [tex]1\frac{1}{7}[/tex] gallons
He has green paint = [tex]1\frac{1}{8}[/tex] gallons
quantity of blue paint = [tex]\frac{7}{8}[/tex] gallons
He plans to use [tex]\frac{3}{4}[/tex] gallon of each paint.
after painting mural, amount of yellow paint left = [tex]1\frac{1}{7}[/tex] - [tex]\frac{3}{4}[/tex] = [tex]\frac{32-21}{28}[/tex] = [tex]\frac{11}{28}[/tex] gallon
Amount of green paint left = [tex]1\frac{1}{8}[/tex] - [tex]\frac{3}{4}[/tex] = [tex]\frac{9-6}{8}[/tex] = [tex]\frac{3}{8}[/tex] gallons
Amount of blue paint left = [tex]\frac{7}{8}[/tex] - [tex]\frac{3}{4}[/tex] = [tex]\frac{7-6}{8}[/tex] = [tex]\frac{1}{8}[/tex] gallons
Mark have left [tex]\frac{11}{28}[/tex] yellow paint, [tex]\frac{3}{8}[/tex] of green paint and [tex]\frac{1}{8}[/tex] of blue paint.
Total amount of paint left = [tex]\frac{11}{28}[/tex] + [tex]\frac{3}{8}[/tex] + [tex]\frac{1}{8}[/tex] = [tex]\frac{25}{28}[/tex]
