Answer 2

Ответ:

Пошаговое объяснение:

(8 - 2 2/7 × 2 11/12) ÷ 2 2/27 = ( 8 - 16/7 × 35/12 ) ÷ 56/27 = (8 - 4 × 5/3 ) × 27/56 = ( 8 - 20/3 ) × 27/56 = 4/3 × 27/56 = 9/14

Answer 3

To solve the expression, let's first convert all the mixed numbers into improper fractions:

8 - 2 2/7 can be written as 8 - (2 * 7 + 2)/7 = 8 - 16/7 = 8 - 2 2/7 = (56/7 - 16/7) = 40/7

2 11/12 can be written as (2 * 12 + 11)/12 = 35/12

2 2/27 can be written as (2 * 27 + 2)/27 = 56/27

Now let's substitute these values back into the expression:

(40/7 * 35/12) : 56/27

To divide fractions, we can multiply by the reciprocal of the divisor:

(40/7 * 35/12) * (27/56)

Next, let's simplify the multiplication:

(40 * 35 * 27) / (7 * 12 * 56)

Now, we can cancel out any common factors between the numerator and denominator:

(5 * 8 * 7 * 35 * 3) / (7 * 2 * 2 * 3 * 2 * 7)

Simplifying further:

(5 * 8 * 35) / (2 * 2 * 2 * 7)

= (5 * 8 * 35) / (8 * 7)

= (5 * 5 * 7) / 7

= (5 * 5)

= 25

Therefore, (8 - 2 2/7 * 2 11/12) : 2 2/27 equals 25.
