ответ: −0,06507937

решение очень лёгкое

Answer 2

To simplify the expression, let's convert the mixed numbers to improper fractions first:

1 5/14 = (14 * 1 + 5) / 14 = 19/14 2 2/7 = (7 * 2 + 2) / 7 = 16/7 8 9/14 = (14 * 8 + 9) / 14 = 121/14

Now, let's substitute the values into the expression:

19/14 - (16/7 - 121/14)

To subtract the fractions within the parentheses, we need a common denominator. The common denominator of 14 and 7 is 14:

19/14 - ((16/7) * (2/2)) - 121/14

Multiplying 16/7 by 2/2:

19/14 - (32/14) - 121/14

Now, the fractions within the parentheses have a common denominator, so we can combine them:

19/14 - 32/14 - 121/14

To subtract these fractions, we simply subtract the numerators while keeping the denominator the same:

(19 - 32 - 121) / 14

Simplifying the numerator:

(-134) / 14 = -67/7

Therefore, the result of the expression 1/5/14 - (2/2/7 - 8/9/14) is -67/7.
