Answer 2

Let's solve the given expressions:

А) 2400:8-74

To solve this expression, we need to perform the operations in the following order: division (:) and subtraction (-).

2400 ÷ 8 = 300 300 - 74 = 226

Therefore, 2400:8-74 equals 226.

Б) 121:11*5+75:3

Again, we need to perform the operations in the correct order: division (:) and multiplication (*) first, then addition (+) and division (:).

121 ÷ 11 = 11 11 × 5 = 55

75 ÷ 3 = 25

Now, we can continue with the addition and division:

55 + 25 = 80

Therefore, 121:11*5+75:3 equals 80.

100-3*6:2

First, we need to perform the multiplication (*) and division (:) operations, and then the subtraction (-).

3 × 6 = 18 18 ÷ 2 = 9

Now we can proceed with the subtraction:

100 - 9 = 91

Therefore, 100-3*6:2 equals 91.

240-105:5+5*0

As before, we start with the division (:) and multiplication (*), and then perform the subtraction (-) and addition (+).

105 ÷ 5 = 21 5 × 0 = 0

Now we can continue:

240 - 21 + 0 = 219

Therefore, 240-105:5+5*0 equals 219.

1258-506

We perform the multiplications (*) first and then the subtraction (-).

125 × 8 = 1000 50 × 6 = 300

Now we can proceed:

1000 - 300 = 700

Therefore, 1258-506 equals 700.

880:8+8*8-8

We start with the division (:) and multiplication (*) operations, and then perform the addition (+) and subtraction (-).

880 ÷ 8 = 110 8 × 8 = 64

Now we can continue:

110 + 64 - 8 = 166

Therefore, 880:8+8*8-8 equals 166.

To summarize: А) 2400:8-74 = 226 Б) 121:115+75:3 = 80 100-36:2 = 91 240-105:5+50 = 219 1258-506 = 700 880:8+88-8 = 166
