Ruby drank 4/5 liter of water Monday before jogging. She drank 2/3 liter of water after her jog. How much water did Ruby drink altogether?

22/15, or  Liters of Water

Step-by-step explanation:

First find a Common Denominator, which in this case would be 15. But, you have to make the numerators numbers that can be with the new common denominator, so multiply 2*5, and that's 10, and 4*3, which is 12. Since the problem is  asking you to find out how much water she drank in total, you can just add the numbers up since the denominators the same. So with the new numbers 10/15, add that with 12/15, and you get 22/15. At this point you can either keep it as 22/15, or you can make it into a mixed number of 1 7/15 as your final answer.
