Question

helen bought 4 gallons of paint to redecorate her family room. if she uses 4/5 of the paint on the family room walls how much paint does Helen have left over?????

Answer 1

4/5 of 4
0.80 x 4 = 3.2
3.2 / 4 = 0.8 gallons used
5/5 = 4 gallons
5/5 - 4/5 = 1/5
0.8 = 1/5
Happy to Help!

Answer 2

She has 1/5 left because the total amount of paint would be 5/5, so you subtract 4/5 from 5/5 and are left to only have 1/5 of paint left. Answer: 1/5 paint left
