Answer 2

Calculation Examples:

Let's solve the given examples step by step:

1. 39:3•4= To solve this, we need to perform the division first, then multiply the result by 4. - Division: 39 divided by 3 equals 13. - Multiplication: 13 multiplied by 4 equals 52.

Therefore, 39:3•4 = 52.

2. 100-3•4= To solve this, we need to perform the multiplication first, then subtract the result from 100. - Multiplication: 3 multiplied by 4 equals 12. - Subtraction: 100 minus 12 equals 88.

Therefore, 100-3•4 = 88.

3. 84-(48+26)= To solve this, we need to perform the addition first, then subtract the result from 84. - Addition: 48 plus 26 equals 74. - Subtraction: 84 minus 74 equals 10.

Therefore, 84-(48+26) = 10.

4. 64:2•3= To solve this, we need to perform the division first, then multiply the result by 3. - Division: 64 divided by 2 equals 32. - Multiplication: 32 multiplied by 3 equals 96.

Therefore, 64:2•3 = 96.

5. 6•9+48:6= To solve this, we need to perform the multiplication first, then perform the division, and finally perform the addition. - Multiplication: 6 multiplied by 9 equals 54. - Division: 48 divided by 6 equals 8. - Addition: 54 plus 8 equals 62.

Therefore, 6•9+48:6 = 62.

6. 23+(75-48)= To solve this, we need to perform the subtraction first, then perform the addition. - Subtraction: 75 minus 48 equals 27. - Addition: 23 plus 27 equals 50.

Therefore, 23+(75-48) = 50.

7. 48:4•8= To solve this, we need to perform the division first, then multiply the result by 8. - Division: 48 divided by 4 equals 12. - Multiplication: 12 multiplied by 8 equals 96.

Therefore, 48:4•8 = 96.

8. 66:3•2-5= To solve this, we need to perform the division first, then perform the multiplication, and finally perform the subtraction. - Division: 66 divided by 3 equals 22. - Multiplication: 22 multiplied by 2 equals 44. - Subtraction: 44 minus 5 equals 39.

Therefore, 66:3•2-5 = 39.

9. 53-(53-40)= To solve this, we need to perform the subtraction inside the parentheses first, then perform the outer subtraction. - Subtraction inside parentheses: 53 minus 40 equals 13. - Subtraction: 53 minus 13 equals 40.

Therefore, 53-(53-40) = 40.

Problem: Цена билета 78 р. Пассажир отдал в кассу 100 р. для покупки 1 билета. Сколько сдачи он должен получить?

To solve this problem, we need to subtract the ticket price from the amount of money the passenger gave to the cashier.

Given: - Ticket price: 78 р. - Amount given to the cashier: 100 р.

To find the change, we subtract the ticket price from the amount given: - Change: 100 р. - 78 р. = 22 р.

Therefore, the passenger should receive 22 р. as change.
