Answer 1

Ответ:1 17/30

Пошаговое объяснение:2 12/17 +1 5/17=3 17/17=4

3 4/5+13/5=6 2/5

10:4-6 2/5:6

2,5-1 1/15=1 17/30

Answer 2

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

First, let's simplify the addition within the parentheses: 2 12/17 + 1 5/17 = 2 + 1 + 12/17 + 5/17 = 3 + 17/17 = 3 + 1 = 4

Next, let's simplify the addition outside the parentheses: 3 4/5 + 13/5 = 3 + 13/5 = 3 + 2 3/5 = 5 3/5

Now, let's simplify the division: (5 3/5) : 6 = 5 3/5 ÷ 6

To divide a mixed number by a whole number, we convert the mixed number to an improper fraction: 5 3/5 = (5 * 5 + 3) / 5 = 28/5

Now, we can perform the division: (28/5) ÷ 6 = 28/5 * 1/6 = 28/30 = 14/15

Finally, let's subtract the result obtained from the previous step from the result of the addition within the parentheses: 4 - (14/15) = 4 - (14/15) = 60/15 - 14/15 = 46/15

Therefore, the simplified value of the given expression is 46/15.
