Answer 2

First, we need to convert the mixed number 5 3/7 to an improper fraction:

5 3/7 = (5*7 + 3)/7 = 38/7

Then we can multiply 38/7 by 4/7:

(5 целых 3/7*4/7) = (38/7 * 4/7) = 152/49

Next, we need to convert the mixed number 9 1/2 to an improper fraction:

9 1/2 = (9*2 + 1)/2 = 19/2

Finally, we can divide 152/49 by 19/2:

(5 целых 3/7*4/7) :9целых 1/2 = (152/49) ÷ (19/2) = (152/49) x (2/19) = 304/931

So the answer is:

(5 целых 3/7*4/7) :9целых 1/2 = 304/931

First, we need to convert the mixed number 6 5/12 to an improper fraction:

6 5/12 = (6*12 + 5)/12 = 77/12

Then we can multiply 77/12 by 2/7:

(6целых 5/12 * 2/7) = (77/12 * 2/7) = 77/42

Next, we need to convert the mixed number 1 5/6 to an improper fraction:

1 5/6 = (1*6 + 5)/6 = 11/6

Finally, we can divide 77/42 by 11/6:

(6целых 5/12 * 2/7) : 1 целую 5/6 = (77/42) ÷ (11/6) = (77/42) x (6/11) = 154/77

So the answer is:

(6целых 5/12 * 2/7) : 1 целую 5/6 = 154/77
