Mark sold 2 7/8 gallons of lemonade. regan sold 2/3 as much as mark. how much did regan sold in gallons? can you solve it step by step ? ?

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:
