Answer 1

380+190=570

90050-219=89831

89831×570=51203670

51203670:90=568929 (6 остались)

Answer 2

Certainly! Here are the given expressions written in a column format with the corresponding operations:

Expression 1: (90050 - 219 * 380 + 190) ÷ 90 Expression 2: (302281 - 12649) ÷ (48 + 3996) Expression 3: (21000 - 308 * 29) ÷ (4 + 14147 ÷ 47)

Now let's solve each expression step by step:

Expression 1:

1. 219 * 380 = 83220
2. 90050 - 83220 + 190 = 6920
3. 6920 ÷ 90 = 76.89 (rounded to two decimal places)

Expression 2:

1. 302281 - 12649 = 289632
2. 48 + 3996 = 4044
3. 289632 ÷ 4044 = 71.60 (rounded to two decimal places)

Expression 3:

1. 308 * 29 = 8942
2. 21000 - 8942 = 12058
3. 14147 ÷ 47 = 301
4. 4 + 301 = 305
5. 12058 ÷ 305 = 39.56 (rounded to two decimal places)

Therefore, the solutions for each expression in a column format are:

Expression 1: 76.89 Expression 2: 71.60 Expression 3: 39.56
