2.83 gallons of paint is used in each room

Solution:

Given that, Jenny used eight-and-a-half gallons of paint to paint three equal size rooms

To find: Gallons of paint used in each room

From given,


\text{Gallons of paint for 3 room } = 8(1)/(2) = 8.5

Thus, 8.5 gallons is used to paint three equal size room

Therefore, Gallons of paint used in each room is found by dividing 8.5 by 3


\text{Gallons of paint in 1 room } = (8.5)/(3) = 2.83

Thus 2.83 gallons of paint is used in each room
