Answer 2

1. 630:(468-398)
1) 468-398=70
2) 630:70=9

2. 167+58•3
1)58•3=174
2)167+174=341

Answer 3

To solve the given expression step by step, let's break it down:

630 : (468 - 398) + 167 + 58 * 3600 - 349 + 54378 + 452 + 49(820 + 170) : 3(370 + 180) : 5(390 + 290) : 4

Step 1: Evaluate the expression inside parentheses

First, let's evaluate the expression inside the parentheses:

468 - 398 = 70

Now, the expression becomes:

630 : 70 + 167 + 58 * 3600 - 349 + 54378 + 452 + 49(820 + 170) : 3(370 + 180) : 5(390 + 290) : 4

Step 2: Perform multiplication and division from left to right

Next, let's perform the multiplication and division operations from left to right:

58 * 3600 = 208,800

49(820 + 170) = 49 * 990 = 48,510

3(370 + 180) = 3 * 550 = 1,650

5(390 + 290) = 5 * 680 = 3,400

Now, the expression becomes:

630 : 70 + 167 + 208,800 - 349 + 54378 + 452 + 48,510 : 1,650 : 3,400 : 4

Step 3: Perform addition and subtraction from left to right

Finally, let's perform the addition and subtraction operations from left to right:

630 : 70 = 9

9 + 167 = 176

176 + 208,800 = 208,976

208,976 - 349 = 208,627

208,627 + 54,378 = 263,005

263,005 + 452 = 263,457

263,457 + 48,510 = 311,967

311,967 : 1,650 = 188

188 : 3,400 = 0.055

0.055 : 4 = 0.014

So, the final result of the expression is 0.014.

Please note that the above calculations were done based on the given expression.
