Mr. Kreider wants to paint two doors and several shutters. It takes 2 1/8 gallons of paint to coat each door and 1 3/5 to coat all of his shutters. If Mr. Kreider buys three 2-gallon cans of paint, does he have enough to complete the job.

Answer:The three 2-gallon cans of paint  is enough  to complete the job.Step-by-step explanation:Given:It takes 2 1/8 gallons of paint to coat each door and 1 3/5 to coat all of shutters. He had three 2-gallon cans of paint.Now, to find that is he have enough paint to complete the job.Total gallons of paint he buys = 3 × 2 = 6 gallons.Then, let the quantity used change to improper fraction from mixed:[tex]2\frac{1}{8} =\frac{17}{8}[/tex] and [tex]1\frac{3}{5}=\frac{8}{5}[/tex].Now, we add the quantity of paints used to paint doors and shutters:[tex]\frac{17}{8}+\frac{8}{5}[/tex][tex]=\frac{85+64}{40}[/tex][tex]=\frac{149}{40}[/tex]Now, subtracting quantity used from the total quantity:[tex]6-\frac{149}{40}[/tex] [tex]=\frac{240-149}{40}[/tex][tex]=\frac{91}{40}[/tex][tex]=2\frac{11}{40}[/tex]So, after painting the two doors and several shutters from 3 cans of 2-gallon paint still 2 11/40 quantity of paint is remaining.Therefore, the three 2-gallon cans of paint is enough to complete the job.
