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?​
slava [35]

<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

Rewrite as a simplified fraction. 2. 14 ‾ = ?
SOVA2 [1]

Answer:

1/7

Step-by-step explanation:

- I can't really tell what the fraction you have is, I am assuming it is 2/14. If that is correct, simplify by finding a common number.

- Ask yourself, what can both be divided by? (Answer is 2)

- Knowing both simplify by 2, divide the numerator (top) and denominator (bottom) by 2.

- You should get 1/7 (2/2 = 1 and 14/2 = 7)

- If you have any further questions on this topic please let me know. I would be glad to help anytime!
