First, let's simplify the expression:
2 5/6 - 2 1/3 = 2 5/6 - 7/3 = (2*3 + 5)/6 - 7/3 = (6 + 5)/6 - 7/3 = 11/6 - 7/3 = (11 - 14)/6 = -3/6 = -1/2
Therefore, the expression becomes:
(-1/2) * (-5 1/7) + 1 1/3 : (-5 6/7)
Next, let's convert -5 1/7 to an improper fraction:
-5 1/7 = -5 * 7/7 + 1/7 = -35/7 + 1/7 = -34/7
Now, substitute the values into the expression:
(-1/2) * (-34/7) + 1 1/3 : (-5 6/7)
Multiplying the first part:
(-1/2) * (-34/7) = 34/14 = 17/7
Now, let's convert 1 1/3 to an improper fraction:
1 1/3 = 3 * 1 + 1/3 = 3 + 1/3 = 10/3
Finally, substitute the values into the expression:
17/7 + 10/3 : (-5 6/7)
Now, we need to add the fractions:
To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 21.
(17/7 3/3) + (10/3 7/7) : -34/7
(51/21) + (70/21) : -34/7
121/21 : -34/7
Now, to divide fractions, we multiply by the reciprocal of the second fraction:
121/21 * -7/34 = -847/714 = -1 133/714
Therefore, the final result is -1 133/714.
First, let's simplify the expression:
2 5/6 - 2 1/3 = 2 5/6 - 7/3 = (2*3 + 5)/6 - 7/3 = (6 + 5)/6 - 7/3 = 11/6 - 7/3 = (11 - 14)/6 = -3/6 = -1/2
Therefore, the expression becomes:
(-1/2) * (-5 1/7) + 1 1/3 : (-5 6/7)
Next, let's convert -5 1/7 to an improper fraction:
-5 1/7 = -5 * 7/7 + 1/7 = -35/7 + 1/7 = -34/7
Now, substitute the values into the expression:
(-1/2) * (-34/7) + 1 1/3 : (-5 6/7)
Multiplying the first part:
(-1/2) * (-34/7) = 34/14 = 17/7
Now, let's convert 1 1/3 to an improper fraction:
1 1/3 = 3 * 1 + 1/3 = 3 + 1/3 = 10/3
Finally, substitute the values into the expression:
17/7 + 10/3 : (-5 6/7)
Now, we need to add the fractions:
To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 21.
(17/7 3/3) + (10/3 7/7) : -34/7
(51/21) + (70/21) : -34/7
121/21 : -34/7
Now, to divide fractions, we multiply by the reciprocal of the second fraction:
121/21 * -7/34 = -847/714 = -1 133/714
Therefore, the final result is -1 133/714.
