OPERASI HITUNG PERKALIAN DAN PEMBAGIAN

Contoh
4 + 4 + 4 = 3 × 4 = 12
7 + 7 + 7 + 7 = 4 × 7 = 28

A. OPERASI HITUNG PERKALIAN
Ayo, kerjakan seperti contoh di atas!
1. 5 + 5 + 5 + 5 = 4 × 5 = 20
2. 6 + 6 + 6 + 6 = ... × ... = ....
3. 6 + 6 + 6 + 6 + 6 = ... × ... = ...
4. 7 + 7 + 7 = ... × ... = ...
5. 7 + 7 + 7 + 7 + 7 = ... × ... = ...
6. 8 + 8 + 8 + 8 = .... × ... = ...
7. 8 + 8 + 8 + 8 + 8 = ... × ... = ...
8. 9 + 9 + 9 = ... × ... = ...
9. 9 + 9 + 9 + 9 + 9 + 9 = ... × ... = ...
10. 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = ... × ... = ...


B. OPERASI HITUNG PEMBAGIAN

18 : 3 = 6
Pengurangan berulang oleh bilangan 3 sebanyak 6 kali.
18 – 3 – 3 – 3 – 3 – 3 – 3 = 0
maka, 18 – 3 – 3 – 3 – 3 – 3 – 3 = 0, berarti 18 : 3 = 6.

1. 9 – 3 – 3 – 3 = 0 9 : 3 = 3
2. 15 – 3 – 3 – 3 – 3 – 3 = 0 . . .
3. 28 – 9 – 9 – 9 = 0 . . .
4. 36 – 6 – 6 – 6 – 6 – 6 – 6 = 0 . . .
5. 42 – 7 – 7 – 7 – 7 – 7 – 7 = 0 . . .
6. 48 – 8 – 8 – 8 – 8 – 8 – 8 = 0 . . .
7. 56 – 7 – 7 – 7 – 7 – 7 – 7 –7 – 7 = 0 . . .
8. 63 – 9 – 9 – 9 – 9 – 9 – 9 – 9 = 0 . . .
9. 64 – 8 – 8 – 8 – 8 – 8 – 8 – 8 – 8 = 0 . . .
10. 72 – 8 – 8 – 8 – 8 – 8 – 8 – 8 – 8 – 8 = 0 . . .
