5.÷5 = 7 × 6 = 18
24 ÷ = ÷ 3 = 6……
Second, see the topic clearly and calculate it carefully.
1. Write directly. (16)
45÷9 = 6×9 = 92-32 = 36+42 =
4×8 = 85-23 = 42÷6 = 25÷5 =
35+32= 9×3 = 18÷9 = 7×5 =
32÷8= 42+5 1= 64-2 1= 56÷7 =
2. Use vertical calculation. (24 points)
50÷6= 39÷4= 73÷9=
46÷9= 27÷5= 29÷7=
3. Is the following calculation correct? Correcting mistakes. (12)
