Answer:

Diana drank 23/15 or 1 8/15 cups of water.

Step-by-step explanation:

We now need to add 7/10 and 5/6.

But first, we need to find the lcm of the denominators. The lcm, or lowest common multiple is 30, which is the lowest number that is a multiple of both 10 and 6.

21/30 + 25/30 = 46/30

46/2 = 23

30/2 = 15

Diana drank 23/15 or 1 8/15 cups of water.
