Question

19) (20,6-16,74). 0,1+(23,4+8,95):100;20) (0,326 +3,724) 100-(0,19682-0,0987): 0,001;​

Answer 1

19)(20,6-16,74)*0,1+(23,4+8,95):100=0,7095

• 20,6-16,74=3,86
• 23,4+8,95=32,35
• 3,86*0,1=0,386
• 32,35:100=0,3235
• 0,386+0.3235=0,7095

20)(0,326+3,724)*100-(0,19682-0,0987):0,001=306,88

• 0,326+3,724=4,05

• 4,05*100=405

• 0,19682-0,0987=0,09812
• 0,09812/0,001=98,12
• 405-98,12=306,88

Answer 2

It appears you've provided two mathematical expressions. Let's solve them one by one:

19. (20.6 - 16.74) / (0.1 + (23.4 + 8.95) / 100)

Let's calculate this step by step:

1. Calculate the value inside the parentheses: 20.6 - 16.74 = 3.86
2. Calculate the value inside the second set of parentheses: 23.4 + 8.95 = 32.35
3. Divide 32.35 by 100: 32.35 / 100 = 0.3235
4. Add 0.1 to the result from step 3: 0.1 + 0.3235 = 0.4235
5. Finally, divide 3.86 by 0.4235: 3.86 / 0.4235 ≈ 9.1213 (rounded to four decimal places)

So, the result of the expression 19) is approximately 9.1213.

20. (0.326 + 3.724) * 100 - (0.19682 - 0.0987) / 0.001

Let's calculate this one step by step:

1. Calculate the value inside the first set of parentheses: 0.326 + 3.724 = 4.05
2. Multiply 4.05 by 100: 4.05 * 100 = 405
3. Calculate the value inside the second set of parentheses: 0.19682 - 0.0987 = 0.09812
4. Divide 0.09812 by 0.001: 0.09812 / 0.001 = 98.12
5. Finally, subtract the result from step 4 from the result in step 2: 405 - 98.12 = 306.88

So, the result of expression 20) is 306.88.
