2. Min had a mark of 26 out of 31 on a science test. That same day, his sister got a mark of 45 out of 52 on a math test. Explain how to find out who got the better mark.
Min: 26 ÷ 31 = 0.83 = 83%
Sister: 45 ÷ 52 = 0.86 = 86%
Min's got 26 out of 31, so you do 26 ÷ 31.
Min's sister got 45 out of 52, so you do 45 ÷ 52
Min's sister got a higher mark!
