Question

3,4*(2/11+9/11)+(2 3/7-3/7)/0,5

Answer 1

Ответ:

7.4

Пошаговое объяснение:

2/11+9/11=1

3.4×1=3.4

2 3/7 - 3/7 = 2

2/0.5 = 4

4 + 3.4 = 7.4

Answer 2

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

First, let's simplify the fractions: 2/11 + 9/11 = 11/11 = 1

Next, let's calculate the multiplication: 3,4 * 1 = 3,4

Moving on to the next part of the expression: 2 3/7 - 3/7 = 16/7 - 3/7 = 13/7

Now, let's deal with the division: 0,5 divided by 13/7 = 0,5 * 7/13 = 3,5/13

Finally, let's calculate the addition: 3,4 + 3,5/13 = (3,4 * 13 + 3,5) / 13 = (44,2 + 3,5) / 13 = 47,7 / 13

The final result is approximately 3.669, rounded to three decimal places.
