Answer 1

А)15,3÷(1+0,25*16)=3.6
б)40,28-22,5÷12,5+1,7=40.18
в)1,6*1,1+1,8÷4=3.6

Answer 2

Calculation A: 15.3 ÷ (1 + 0.25 * 16)

To solve this calculation, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Let's break down the calculation step by step:

1. First, we need to calculate 0.25 * 16, which equals 4. 2. Next, we need to add 1 to the result of the previous step, which gives us 5. 3. Finally, we divide 15.3 by the result of the previous step.

So, the calculation becomes:

15.3 ÷ 5 = 3.06

Therefore, the result of calculation A is 3.06.

Calculation B: 40.28 - 22.5 ÷ 12.5 + 1.7

Let's solve this calculation step by step:

1. First, we need to calculate 22.5 ÷ 12.5, which equals 1.8. 2. Next, we subtract the result of the previous step from 40.28, which gives us 38.48. 3. Finally, we add 1.7 to the result of the previous step.

So, the calculation becomes:

38.48 + 1.7 = 40.18

Therefore, the result of calculation B is 40.18.

Calculation C: 1.6 * 1.1 + 1.8 ÷ 4

Let's solve this calculation step by step:

1. First, we need to calculate 1.6 multiplied by 1.1, which equals 1.76. 2. Next, we need to calculate 1.8 divided by 4, which equals 0.45. 3. Finally, we add the result of the previous step to the result of the first step.

So, the calculation becomes:

1.76 + 0.45 = 2.21

Therefore, the result of calculation C is 2.21.

To summarize: - Calculation A: 15.3 ÷ (1 + 0.25 * 16) = 3.06 - Calculation B: 40.28 - 22.5 ÷ 12.5 + 1.7 = 40.18 - Calculation C: 1.6 * 1.1 + 1.8 ÷ 4 = 2.21
