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](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ofed5kmq2m0iw5vv8w6udh2v2jsffton8a.png)
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](https://img.qammunity.org/2021/formulas/mathematics/middle-school/zsnbmsyk5k39cnoxxzr8vh1ctlfctl3vbt.png)
Thus 2.83 gallons of paint is used in each room
