liam has 8 3/4 gallons of paint. he wants to use 2/5 of paint to paint his livingroom. how many gallons of paint will liam use?

<u>Answer:</u>

Liam will use 3.5 gallons of paint to paint his living room

<u>Solution:</u>

Given that Liam has $8 \frac{3}{4}$ gallons of paint.

He uses $\frac{2}{5}$ of paint to paint his living room

We need to find how many gallons of paint will Liam use

The gallons of paint Liam used can be found as follows:

Amount of paint Liam has = $8 \frac{3}{4}$ gallons

Converting mixed fraction $8 \frac{3}{4}$ to decimal we get 8.75

Amount of paint used = 2/5th of available amount

$= \frac{2}{5} \times 8.75=3.5 \text { or } 3 \frac{1}{2} \text { gallons }$

Hence Liam will use 3.5 gallons of paint to paint his living room
