把下列各分數由小到大排列出來:
1-1/8,13/7,15/9,1-3/12
當然用通分母
(eg.1-1/8=6804/6084),

但.那樣計數的時間很費時 如何好呀?????

✔ 最佳答案
You can change it to decimal.

1-1/8 is approximate 1.125
13/7 is approximate 1.857
15/9 is approximate 1.667
1-3/12 is approximate 1.25

so if you have to arrange it in order from teh lowest to highest, it will be
1-1/8, 1-3/12, 15/9, 13/7

Hope it help.

假分數可以轉為帶分數

所以沒有帶分數大一点
