Answer 2

1) Решение:

Let's solve each equation step by step:

1) 13806 divided by 531: ``` 13806 ÷ 531 ``` The quotient is 26.

2) 30240 divided by 420: ``` 30240 ÷ 420 ``` The quotient is 72.

3) 7009 multiplied by 24: ``` 7009 × 24 ``` The product is 168,216.

4) 5060 multiplied by 73: ``` 5060 × 73 ``` The product is 369,380.

5) 1000 minus 100 divided by 5 multiplied by the sum of 2 and 8: ``` 1000 - 100 ÷ 5 × (2 + 8) ``` First, calculate the expression inside the parentheses: ``` 1000 - 100 ÷ 5 × 10 ``` Next, perform the division: ``` 1000 - 20 × 10 ``` Finally, perform the multiplication and subtraction: ``` 1000 - 200 ``` The result is 800.

6) 1000 minus the result of 100 divided by 5 multiplied by 2 plus 8: ``` 1000 - (100 ÷ 5 × 2 + 8) ``` First, perform the multiplication and addition inside the parentheses: ``` 1000 - (100 ÷ 5 × 2 + 8) 1000 - (100 ÷ 5 × 2 + 8) 1000 - (20 × 2 + 8) 1000 - (40 + 8) ``` Next, perform the addition: ``` 1000 - 48 ``` The result is 952.

2) Решение:

Let's solve each equation step by step:

1) 208 multiplied by 153: ``` 208 × 153 ``` The product is 31,824.

2) 120 multiplied by 315: ``` 120 × 315 ``` The product is 37,800.

3) 206 multiplied by 407: ``` 206 × 407 ``` The product is 83,842.

4) 380 multiplied by 104: ``` 380 × 104 ``` The product is 39,520.

3) Решение:

We have the following expressions:

1) 5 days minus 18 hours: ``` 5 days - 18 hours ``` To convert hours to minutes, we multiply by 60: ``` 5 days - 18 hours = 5 days - 18 hours × 60 minutes/hour = 5 days - 1080 minutes ```

2) 2 hours minus 35 minutes: ``` 2 hours - 35 minutes ``` To convert hours to minutes, we multiply by 60: ``` 2 hours - 35 minutes = 2 hours × 60 minutes/hour - 35 minutes = 120 minutes - 35 minutes ```

3) 9 minutes minus 24 hours: ``` 9 minutes - 24 hours ``` To convert hours to minutes, we multiply by 60: ``` 9 minutes - 24 hours = 9 minutes - 24 hours × 60 minutes/hour = 9 minutes - 1440 minutes ```

Please note that I'm unable to continue the calculation because the expression is incomplete. If you provide the missing part, I'll be happy to assist you further.
