Answer 2

Ответ:

17/12:3=17/36

2/5-2/5*(2-1 1/12)=1/30

Answer 3

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

17/12:3 is equivalent to dividing 17/12 by 3. To divide fractions, we multiply the numerator of the first fraction by the denominator of the second fraction and the denominator of the first fraction by the numerator of the second fraction. Thus, the calculation becomes:

(17/12) / 3 = (17/12) * (1/3) = 17/36.

Now let's simplify the second part of the expression:

2/5 - 2/5 * (2 - 1 1/12).

First, let's calculate the value inside the parentheses:

2 - 1 1/12 = 2 - (1 + 1/12) = 2 - 13/12 = 24/12 - 13/12 = 11/12.

Now substitute this value back into the expression:

2/5 - 2/5 * (11/12).

To multiply fractions, multiply the numerators together and the denominators together:

2/5 * (11/12) = (2 * 11) / (5 * 12) = 22/60.

Now subtract this value from 2/5:

2/5 - 22/60.

To subtract fractions, we need to have a common denominator. The least common multiple (LCM) of 5 and 60 is 60. So, we convert both fractions to have a denominator of 60:

(2/5) * (12/12) - (22/60) = 24/60 - 22/60 = (24 - 22) / 60 = 2/60.

Finally, we simplify the fraction:

2/60 = 1/30.

Therefore, 17/12:3 - 2/5 * (2 - 1 1/12) equals 1/30.
