Answer 2

Sure, I can help you solve these arithmetic expressions step by step. Let's tackle each one:

1. 154 • 78 + 3900 : 65 - 216 • 53

Step 1: Perform multiplication and division from left to right. 154 • 78 = 12,012 3900 : 65 = 60 216 • 53 = 11,448

Step 2: Perform addition and subtraction from left to right. 12,012 + 60 = 12,072 12,072 - 11,448 = 624

2. 16,728 : 82 - 5580 : 45 + 726 • 29

Step 1: Perform division from left to right. 16,728 : 82 = 204 5580 : 45 = 124

Step 2: Perform multiplication and addition/subtraction from left to right. 204 - 124 = 80 726 • 29 = 21,054 80 + 21,054 = 21,134

3. (39,002 - 37,236) • 205 + 115 • 78

Step 1: Perform the subtraction and multiplication. 39,002 - 37,236 = 1,766 1,766 • 205 = 361,330

Step 2: Perform the addition. 361,330 + 115 • 78 = 361,330 + 8970 = 370,300

4. 875 • 480 - 406 • (50,004 - 48,986)

Step 1: Perform the subtraction inside the parentheses. 50,004 - 48,986 = 1,018

Step 2: Perform the multiplications. 875 • 480 = 420,000 406 • 1,018 = 413,308

Step 3: Perform the final subtraction. 420,000 - 413,308 = 6,692

5. (21,518 : 53 - 24,332 : 79) • 267

Step 1: Perform the divisions. 21,518 : 53 ≈ 406.2264 (rounded to four decimal places) 24,332 : 79 ≈ 308.9114 (rounded to four decimal places)

Step 2: Perform the subtraction and multiplication. 406.2264 - 308.9114 ≈ 97.315 (rounded to three decimal places) 97.315 • 267 ≈ 25,998.105 (rounded to three decimal places)

6. (53,734 : 67 - 59,925 : 85) • 436

Step 1: Perform the divisions. 53,734 : 67 ≈ 801.4925 (rounded to four decimal places) 59,925 : 85 ≈ 705 (rounded to the nearest integer)

Step 2: Perform the subtraction and multiplication. 801.4925 - 705 ≈ 96.4925 (rounded to four decimal places) 96.4925 • 436 ≈ 42,030.954 (rounded to three decimal places)

7. (327 • 84 + 207,673) : 47

Step 1: Perform the multiplication and addition. 327 • 84 = 27,468 27,468 + 207,673 = 235,141

Step 2: Perform the division. 235,141 : 47 = 5,001

8. (924 • 93 + 30,271) : 29

Step 1: Perform the multiplication and addition. 924 • 93 = 85,932 85,932 + 30,271 = 116,203

Step 2: Perform the division. 116,203 : 29 = 4,007

9. (216 • 28 - 463,680 : 92) • (86 • 64 - 4496)

Step 1: Perform the multiplication and division. 216 • 28 = 6,048 463,680 : 92 = 5,040

Step 2: Perform the subtraction. 6,048 - 5,040 = 1,008

Step 3: Perform the final multiplication. 1,008 • (86 • 64 - 4496) = 1,008 • (5,504 - 4,496) = 1,008 • 1,008 = 1,016,064

10. (1004 • 19 - 75,110 : 37) : (408 • 435 - 177,479)

Step 1: Perform the multiplication and division inside the parentheses. 1004 • 19 = 19,076 75,110 : 37 = 2,030

408 • 435 = 177,480 177,480 - 177,479 = 1

Step 2: Perform the final division. (19,076 - 2,030) : 1 = 17,046

11. 61 - (1428 : 136 + 4.3) • 3.4

Step 1: Perform the division and addition inside the parentheses. 1428 : 136 ≈ 10.5 (rounded to one decimal place) 10.5 + 4.3 ≈ 14.8 (rounded to one decimal place)

Step 2: Perform the final subtraction and multiplication. 61 - 14.8 • 3.4 ≈ 61 - 50.32 ≈ 10.68 (rounded to two decimal places)

12. 40 - (2550 : 204 - 6.9) • 6.7

Step 1: Perform the division and subtraction inside the parentheses. 2550 : 204 ≈ 12.5 (rounded to one decimal place) 12.5 - 6.9 ≈ 5.6 (rounded to one decimal place)

Step 2: Perform the final subtraction and multiplication. 40 - 5.6 • 6.7 ≈ 40 - 37.52 ≈ 2.48 (rounded to two decimal places)

13. 37.72 : 4.6 - (1.43 + 2.728) • 1.5

Step 1: Perform the division and addition inside the parentheses. 37.72 : 4.6 ≈ 8.193 (rounded to three decimal places) 1.43 + 2.728 ≈ 4.158 (rounded to three decimal places)

Step 2: Perform the final subtraction and multiplication. 8.193 - 4.158 • 1.5 ≈ 8.193 - 6.237 ≈ 1.956 (rounded to three decimal places)

I hope that helps! If you have any further questions or need clarification, feel free to ask.
