Answer 1

1) (1494+1854):(1104-1077)•378
1494+1854=3348
1104-1077=27
3348:27=124
124*378=46872

2) 27463•0+37400:136
27463*0=0
37400:136=275
0+275=275

Answer 2

Let's solve each expression step by step:

1. (1494 + 1854) : (1104 - 1077) • 378

Step 1: Evaluate inside the parentheses. 1494 + 1854 = 3348 1104 - 1077 = 27

Step 2: Perform the division operation. 3348 ÷ 27 = 124

Step 3: Perform the multiplication operation. 124 • 378 = 46952

The result of the expression is 46952.

2. 27463 • 0 + 37400 : 136

Step 1: Perform the multiplication operation. 27463 • 0 = 0

Step 2: Perform the division operation. 37400 ÷ 136 ≈ 275

Step 3: Perform the addition operation. 0 + 275 = 275

The result of the expression is 275.

3. (76 • 144 : 19 - 3928) • 751 + 60 521

Step 1: Evaluate inside the parentheses. 76 • 144 = 10944 10944 ÷ 19 ≈ 575.79 (rounded to two decimal places) 575.79 - 3928 ≈ -3352.21 (rounded to two decimal places)

Step 2: Perform the multiplication operation. -3352.21 • 751 ≈ -2518555.27 (rounded to two decimal places)

Step 3: Perform the addition operation. -2518555.27 + 60521 ≈ -2458034.27 (rounded to two decimal places)

The result of the expression is approximately -2,458,034.27.
