Answer: 3.5 gallons
Step-by-step explanation:
From the question, we are told that Chanasia has 8.75 gallons of paint and that she wants to use 2/5 of the paint to paint her living room.
The gallons of paint that Chanasia will use be gotten by multiplying 2/5 by 8.75 gallons. This will be:
= 2/5 × 8.75 gallons
= 0.4 × 8.75 gallons
= 3.5 gallons.
This means that Chanasia will use 3.5 gallons to paint her living room
