Question

1) 40: (19 13/17-3 13/17)+(5 3/5-2 4/5):7= 3) 70 1​

Answer 1

Ответ:

2,9

Пошаговое объяснение:

1) 19 13/17 - 3 13/17 = 16

2) 40 : 16 = 2,5

3) 5 3/5 - 2 4/5 = 4 8/5 - 2 4/5 = 2 4/5

4) 2 4/5 : 7 = 14/5 * 1/7 = 2/5 * 1/1 = 2/5 = 0,4

5) 2,5 + 0,4 = 2,9

Answer 2

To solve the given expression, let's break it down step by step:

1. Calculate the value inside the parentheses: 19 13/17 - 3 13/17 = (19 - 3) + (13/17 - 13/17) = 16 + 0 = 16

2. Calculate the value inside the second parentheses: 5 3/5 - 2 4/5 = (5 - 2) + (3/5 - 4/5) = 3 + (-1/5) = 2 4/5

3. Divide the result of step 2 by 7: 2 4/5 ÷ 7 = (2 + 4/5) ÷ 7 = (10/5 + 4/5) ÷ 7 = 14/5 ÷ 7 = 14/5 × 1/7 = 14/35 = 2/5

4. Add the result of step 1 to the result of step 3: 16 + 2/5 = 16 + 2/5 = 80/5 + 2/5 = 82/5

So, the final result is 82/5, which is approximately equal to 16.4.
