答題卡:
一、用簡便方法計算。
1. 700÷60
700÷60 = (700÷10) ÷ (60÷10) = 70 ÷ 6 = 11......40 = 11(60/6) + 40/60 = 11......40(轉化為分數為 11(2/3)的商,余40,或寫作混合數)
簡便寫法:700÷60 = 11......40 或 11(2/3)(商用分數表示)
最終簡答:11......40(或 11(2/3))
2. 980÷70
980÷70 = (980÷10) ÷ (70÷10) = 98 ÷ 7 = 14
簡便寫法:980÷70 = 14
3. 800÷70
800÷70 = (800÷10) ÷ (70÷10) = 80 ÷ 7 = 11......30 = 11(7/7) + 30/70 = 11(3/7)(商用分數表示)
簡便寫法:800÷70 = 11......30 或 11(3/7)
最終
