Question

Bailey has 5 gallons of lemonade for his school picnic. At the end of the day he has 1 1/3 gallons of lemonade left. How much lemonade was used?

Answer 1

3 2/3 used up

Explanation:

You can set it up as 15/3 - 4/3 = 11/3, which is equal to 3 2/3 ;)

Answer 2

so he had 5 gal at end of day he had 1 and 1/3 left
so 5-x=1 1/3
add x to both sides
5=1 1/3+x
5=15/5
1 1/3=4/3
15/3=4/3+x
subtract 4/3 from both sides
11/3=x
3 2/3 was used up
