Answer 3

Let's solve the given expressions step by step:

1. (57 * 9 + 87) / 6: First, we perform the multiplication inside the parentheses: 57 * 9 = 513. Then, we add 513 and 87: 513 + 87 = 600. Finally, we divide 600 by 6: 600 / 6 = 100.

   Therefore, the result of this expression is 100.

2. (648 / 4 - 78) * 4: First, we perform the division inside the parentheses: 648 / 4 = 162. Then, we subtract 162 and 78: 162 - 78 = 84. Finally, we multiply 84 by 4: 84 * 4 = 336.

   Therefore, the result of this expression is 336.

3. (807 - 55 * 6) / 9: First, we perform the multiplication inside the parentheses: 55 * 6 = 330. Then, we subtract 330 from 807: 807 - 330 = 477. Finally, we divide 477 by 9: 477 / 9 = 53.

   Therefore, the result of this expression is 53.

4. (900 - 755 / 5) / 7: First, we perform the division inside the parentheses: 755 / 5 = 151. Then, we subtract 151 from 900: 900 - 151 = 749. Finally, we divide 749 by 7: 749 / 7 = 107.

   Therefore, the result of this expression is 107.

5. 137 * 6 / 2: First, we perform the multiplication: 137 * 6 = 822. Then, we divide 822 by 2: 822 / 2 = 411.

   Therefore, the result of this expression is 411.

6. 219 / 3 * 8: First, we perform the division: 219 / 3 = 73. Then, we multiply 73 by 8: 73 * 8 = 584.

   Therefore, the result of this expression is 584.

To summarize, the results of the given expressions are as follows:

1. (57*9+87)/6 = 100
2. (648/4-78)*4 = 336
3. (807-55*6)/9 = 53
4. (900-755/5)/7 = 107
5. 137*6/2 = 411
6. 219/3*8 = 584
