Answer:
Step-by-step explanation:
The phrase "twice as much lemonade" tells you that if Mark sold 2 gallons and Regan sold twice as much as Mark, then Regan sold 2 * 2 which is 4 gallons, right? It's the same with the "2/3 as much". But since 2/3 is less than 1, the amount after you multiply some number by 2/3 is going to be less than the original number.
If Mark sold 2 7/8 gallons and Regan sold 2/3 as much, then Regan sold
I teach my algebra students to change that mixed fraction into an improper to make the multiplication easier:
5 1/3+1 1/3
= 15/3+1/3 3/3+1/3
=20/3
= 18/3+2/3
=6 2/3
OR
when both fractions are the same, you can just add them this way:
5 1/3 + 1/3
= 5+1 + 1/3+1/3
=6+2/3
= 6 2/3
