Question

Решите примеры пожалуйста обязательно по действиям: 1) (0,7:1,4-0,02):0,012+1,6•(0,548-0,023)=2) (1,184:3,2+0,832:0,4):0,5+1,5=3) 4,96:10+35,8:100-0,0042=3) (0,04+3,59)•(7,35+2,65):300=​

Answer 1

1) 1. 0,7:1,4 = 0.5

2. 0.5 - 0.02 = 0.48

3. 0.548 - 0.023= 0.525

4.0.48:0.012 = 40

5. 1.6 × 0.525 = 0.84

6. 40 + 0.84 = 40.84

2) 1. 1.184:3.2 = 0.37

2. 0.832:0.4 = 2.08

3. 0.37 + 2.08 = 2.45

4. 2.45:0.5 = 4.9

5. 4.9 + 1.5 = 6.4

3) 1. 4.96:10 = 0.496

2. 35.8:100 = 0.358

3. 0.358 + 0.496 = 0.854

4. 0.854 - 0.0042 = 0.8498

4) 1. 0.04 + 3.59 = 3.63

2. 7.35 + 2.65 = 10

3. 3.63 × 10 = 36.3

4. 36.3 : 300= 0.121

Answer 3

1. (0.7 / 1.4 - 0.02) / 0.012 + 1.6 * (0.548 - 0.023)

Step 1: Calculate within parentheses. 0.7 / 1.4 = 0.5

Step 2: Subtract 0.02 from 0.5. 0.5 - 0.02 = 0.48

Step 3: Divide the result from Step 2 by 0.012. 0.48 / 0.012 = 40

Step 4: Calculate within parentheses. 0.548 - 0.023 = 0.525

Step 5: Multiply 1.6 by the result from Step 4. 1.6 * 0.525 = 0.84

Step 6: Add the results from Step 3 and Step 5. 40 + 0.84 = 40.84

Therefore, the solution is 40.84.

2. (1.184 / 3.2 + 0.832 / 0.4) / 0.5 + 1.5

Step 1: Divide 1.184 by 3.2. 1.184 / 3.2 = 0.37

Step 2: Divide 0.832 by 0.4. 0.832 / 0.4 = 2.08

Step 3: Add the results from Step 1 and Step 2. 0.37 + 2.08 = 2.45

Step 4: Divide the result from Step 3 by 0.5. 2.45 / 0.5 = 4.9

Step 5: Add 4.9 to 1.5. 4.9 + 1.5 = 6.4

Therefore, the solution is 6.4.

3. 4.96 / 10 + 35.8 / 100 - 0.0042

Step 1: Divide 4.96 by 10. 4.96 / 10 = 0.496

Step 2: Divide 35.8 by 100. 35.8 / 100 = 0.358

Step 3: Subtract 0.0042 from the result from Step 2. 0.358 - 0.0042 = 0.3538

Step 4: Add the results from Step 1 and Step 3. 0.496 + 0.3538 = 0.8498

Therefore, the solution is 0.8498.

4. (0.04 + 3.59) * (7.35 + 2.65) / 300

Step 1: Add 0.04 and 3.59. 0.04 + 3.59 = 3.63

Step 2: Add 7.35 and 2.65. 7.35 + 2.65 = 10

Step 3: Multiply the results from Step 1 and Step 2. 3.63 * 10 = 36.3

Step 4: Divide the result from Step 3 by 300. 36.3 / 300 = 0.121

Therefore, the solution is 0.121.
