Marcus has 2 3/5 gallon of blue paint. He will use 7/10 of the paint for his room. how much blue paint will Marcus use for his room? Write and solve an equation to find the answer.

1.82 gallon or 6.9 litres

Step-by-step explanation:

Given

Gallon of blue paint = 2 3/5 = (5*2+3) / 5 = 13/5 gallon

Fraction of paint used in painting the room = 7/10 of paint available

= 7/10 * 13/5 = 91/50 gallon

= 1 41/50 gallon = 1.82 gallon

**converting gallon into litres

one gallon is equal to 3.79 litres

hence 91/50 gallon = 91/50*3.79 litres = 6.9 litres
