Liam has 8 3/4 gallons of paint. He wants to use 2/5 of the paint to paint his living room. How many gallons of paint will Liam use?

I think that I would need to take 8 3/4 - 2/5=8 7/20

Can you tell me if I got this answer right or wrong and if I got it wrong how would I go about solving this problem?

Thank you

what type of math would you use to figure how much?
Multiplication!!

8 3/4 times 2/5 =

see if you can get it from there
