Answer:
37/56
Explanation:
If Jisoo drank 3/8 of a quart of chocolate milk, and his friend Andrew drank 2/7 of the same quart, the amount they drank altogether will be the sum of the amount they drank individually
Total = 3/8 + 2/7
Find the LCM
Total = 3(7)+8(2)/56
Total = (21+16)/56
Total = 37/56
Hence they drank 37/56 of the quartz altogether
