Answer 1

$\frac{2 \frac{5}{9}-1 \frac{20}{21} }{1 \frac{8}{49}}+ \frac{1 \frac{8}{9}}{6} = \frac{ \frac{23}{9}- \frac{41}{21}}{ \frac{57}{49} }+ \frac{\frac{17}{9}}{6} = \frac{ \frac{38}{63}}{ \frac{57}{49}}+\frac{17}{54}= \frac{14}{27}+ \frac{17}{54} = \frac{5}{6}$

Answer 3

Calculating the Expression

The given expression is: (2 5/9 - 1 20/21) : 1 8/49 + 1 8/9 : 6

Let's break it down step by step using the provided search result snippet:

1. (2 5/9 - 1 20/21) - This simplifies to: 23/9 - 41/21 = 161/63 - 123/63 = 38/63

2. 38/63 : 1 8/49 - This simplifies to: 38/63 : 57/49 = 38/63 * 49/57 = 2/63 * 49/3 = 2/9 * 7/3 = 14/27

3. 1 8/9 : 6 - This simplifies to: 17/9 : 6 = 17/9 * 1/6 = 17/54

Now, we have the following values: - (2 5/9 - 1 20/21) = 38/63 - 38/63 : 1 8/49 = 14/27 - 1 8/9 : 6 = 17/54

Finally, we calculate: - 14/27 - 17/54 = 28/57 - 17/57 = 11/57

So, the value of the given expression is 11/57.
