Question

A)(8 целых 3/17-7 целых 15/17)+3 целых 16/17 б)(8 -4 целых 3/11)+2 целых 8/11

Answer 1

Ответ:

а) 4 целых 4/17

б) 6 целых 5/11

Answer 2

Let's simplify the given expressions:

a) (8 целых 3/17 - 7 целых 15/17) + 3 целых 16/17

To add or subtract mixed numbers, we need to first convert them into improper fractions. Let's do that for the first part:

8 целых 3/17 = (8 * 17 + 3)/17 = 139/17

7 целых 15/17 = (7 * 17 + 15)/17 = 124/17

Now we can rewrite the expression:

(139/17 - 124/17) + 3 целых 16/17

Combining the fractions:

(139/17 - 124/17) = 15/17

Now we have:

(15/17) + 3 целых 16/17

To add the whole numbers and fractions, we need to convert the whole numbers into fractions with the same denominator:

3 целых 16/17 = (3 * 17 + 16)/17 = 67/17

Now we can add the fractions:

(15/17) + (67/17) = (15 + 67)/17 = 82/17

Therefore, the result is:

82/17

b) (8 - 4 целых 3/11) + 2 целых 8/11

Let's convert the mixed numbers into improper fractions:

4 целых 3/11 = (4 * 11 + 3)/11 = 47/11

2 целых 8/11 = (2 * 11 + 8)/11 = 30/11

Now we can rewrite the expression:

(8 - 47/11) + 30/11

To subtract fractions, we need to have a common denominator. In this case, the denominators are already the same, so we can proceed:

(8 - 47/11) = (88/11 - 47/11) = 41/11

Now we have:

(41/11) + 30/11 = (41 + 30)/11 = 71/11

Therefore, the result is:

71/11
