Answer 1

Ответ: (по действиям)

(3-3,8:5. 2/11)*3/17+(18-8. 2/3):1.1/6=

1) 3,8:5. 2/11= 38/10:57/11=38/10*11/57= 11/15

2) 3- 11/15=2.15/15-11/15=2.4/15

3) 2.4/15*3/17=34/15*3/17=2/5

4)18-8. 2/3 = 17.3/3-8.2/3=9.1/3

5) 9.1/3:1.1/6=28/3 :7/6=28/3 *6/7=8

6) 2/5+8=8.2/5

(13.2/7:31/70-28,5):6,75+20. 2/3-19.9/10=

1) 13.2/7:31/70 = 93/7 *70/31=30

2) 30-28,5=1,5

3) 1,5:6,75=150:675=6/27=2/9

4) 20.2/3-19.9/10 = 20.20/30-19.27/30=19.50/30-19.27/30=23/30

5) 2/9 +23/30 = 20/90 +69/90=89/90

Answer 3

Let's break down the expression step by step:

1. Inside the parentheses: a. 3 - 3 = 0 b. 8 ÷ 5 = 1.6 c. 2 + 11 = 13

2. Now, let's calculate what's inside the first set of parentheses: (0, 1.6, 13) = (0, 1.6, 13)

3. Inside the second set of parentheses: a. 18 - 8 = 10 b. 2 ÷ 3 = 0.6667 (rounded to 4 decimal places)

4. Now, let's calculate what's inside the second set of parentheses: (10, 0.6667) = (10, 0.6667)

5. Now, we'll perform the division and multiplication operations outside the parentheses: a. (0, 1.6, 13) × 3/17 = (0 × 3/17, 1.6 × 3/17, 13 × 3/17) = (0, 0.2824, 2.4118) b. (10, 0.6667) ÷ 2/16 = (10 ÷ 2/16, 0.6667 ÷ 2/16) = (10 × 16/2, 0.6667 × 16/2) = (80, 5.3334)

6. Now, let's add the results of the previous steps: a. (0, 0.2824, 2.4118) + (80, 5.3334) = (0 + 80, 0.2824 + 5.3334) = (80, 5.6158)

So, the final result of the expression is (80, 5.6158).
