No, it cannot.
The average of 119 and 77 is 98.
Yes and it is 8/11
sqrt(77)/9 cannot be simplified.
Find their GCF and divide each of them by it. Get 8/17
14/77 = 2/11
1/3 + 3/5 + 7/10 = 49/30 or 119/30
1309
-33/119 + -3/77 = -3/7*(11/17 + 1/11) = -3/7*(121/187 + 17/187) = -3/7*138/187 = -414/1309
Their greatest common factor is 2, so divide both parts by 2. That gives you 77 over 108.
Their greatest common factor is 7, so divide both parts by 7. That gives you 11 over 16.
