Answer 2

Let's solve each expression step by step:

1. (156-96:12):(4:2) First, we evaluate the division inside parentheses: 96 divided by 12 equals 8. Next, we evaluate the division outside parentheses: 156 divided by 8 equals 19.5. Finally, we evaluate the division inside parentheses again: 4 divided by 2 equals 2. Therefore, (156-96:12):(4:2) equals 19.5 divided by 2, which is equal to 9.75.

2. 4689×5+97308 Multiply 4689 by 5: 23445. Add 97308 to the result: 120753. Therefore, 4689×5+97308 equals 120753.

3. 90 000 - 6×2509 Multiply 6 by 2509: 15054. Subtract 15054 from 90,000: 74,946. Therefore, 90,000 - 6×2509 equals 74,946.

4. 76 090×4-5673 Multiply 76,090 by 4: 304,360. Subtract 5,673 from the result: 298,687. Therefore, 76,090×4-5673 equals 298,687.

5. 1485:5×4 Divide 1485 by 5: 297. Multiply 297 by 4: 1,188. Therefore, 1485:5×4 equals 1,188.

6. 2496:8×7 Divide 2496 by 8: 312. Multiply 312 by 7: 2,184. Therefore, 2496:8×7 equals 2,184.

7. 9999:9×8 Divide 9999 by 9: 1111. Multiply 1111 by 8: 8,888. Therefore, 9999:9×8 equals 8,888.

To summarize:

• (156-96:12):(4:2) = 9.75
• 4689×5+97308 = 120753
• 90,000 - 6×2509 = 74,946
• 76,090×4-5673 = 298,687
• 1485:5×4 = 1,188
• 2496:8×7 = 2,184
• 9999:9×8 = 8,888
