Answer 2

Let's solve the equations one by one:

1. 70 ÷ 14 × 13 = First, we perform the division: 70 ÷ 14 = 5. Then we multiply the result by 13: 5 × 13 = 65. Therefore, 70 ÷ 14 × 13 = 65.

2. 54 ÷ (90 ÷ 5) = Inside the parentheses, we perform the division: 90 ÷ 5 = 18. Then we divide 54 by the result: 54 ÷ 18 = 3. Therefore, 54 ÷ (90 ÷ 5) = 3.

3. 92 ÷ (46 ÷ 2) × 2 = Inside the parentheses, we perform the division: 46 ÷ 2 = 23. Then we divide 92 by the result: 92 ÷ 23 = 4. Finally, we multiply the result by 2: 4 × 2 = 8. Therefore, 92 ÷ (46 ÷ 2) × 2 = 8.

4. (610 + 20) ÷ 7 ÷ 90 = First, we perform the addition inside the parentheses: 610 + 20 = 630. Then we divide the result by 7: 630 ÷ 7 = 90. Finally, we divide 90 by 90: 90 ÷ 90 = 1. Therefore, (610 + 20) ÷ 7 ÷ 90 = 1.

5. 170 + 320 - 200 = First, we perform the addition: 170 + 320 = 490. Then we subtract 200 from the result: 490 - 200 = 290. Therefore, 170 + 320 - 200 = 290.

6. 480 ÷ 6 + 780 = First, we perform the division: 480 ÷ 6 = 80. Then we add 780 to the result: 80 + 780 = 860. Therefore, 480 ÷ 6 + 780 = 860.

To summarize:

1. 70 ÷ 14 × 13 = 65
2. 54 ÷ (90 ÷ 5) = 3
3. 92 ÷ (46 ÷ 2) × 2 = 8
4. (610 + 20) ÷ 7 ÷ 90 = 1
5. 170 + 320 - 200 = 290
6. 480 ÷ 6 + 780 = 860
