2. Вычисли 48:6×8= 56:7 × 9 = 63:7×5= 36:4×8= 72:8×6= 90:10 × 3 = 7×4-12+18= (35-9) × 3 = (28-13) × (54 : 9) =

1. $$48 : 6 \times 8 = 8 \times 8 = 64$$
2. $$56 : 7 \times 9 = 8 \times 9 = 72$$
3. $$63 : 7 \times 5 = 9 \times 5 = 45$$
4. $$36 : 4 \times 8 = 9 \times 8 = 72$$
5. $$72 : 8 \times 6 = 9 \times 6 = 54$$
6. $$90 : 10 \times 3 = 9 \times 3 = 27$$
7. $$7 \times 4 - 12 + 18 = 28 - 12 + 18 = 16 + 18 = 34$$
8. $$(35 - 9) \times 3 = 26 \times 3 = 78$$
9. $$(28 - 13) \times (54 : 9) = 15 \times 6 = 90$$

Ответ: 1) 64; 2) 72; 3) 45; 4) 72; 5) 54; 6) 27; 7) 34; 8) 78; 9) 90.
