Here are 7 7 same-sized cups filled with water which will be used for watering plants. Fred used 1 3 3 1 ​ of each cup of water. Janice used 1 4 4 1 ​ of each cup of water. Approximately how many cups of water remain?

2 11/12

Step-by-step explanation:

total amount fred used = 1/3 x 7 = 7/3

total amount Janice used = 1/4 x 7 = 7/4

total amount used =

7/3 + 7/4

(28 + 21) / 12 = 49 / 12 = 4 1/12

Amount left = 7 - 4 1/12 = 2 11/12
