2/55 = 14/385
6/77 = 30/385
44/385 = 4/35
2/7+8/11 = 78/77
(4/5) + (2/11) = (44/55) + (10/55) = 54/55
Factors of 77: 1, 7, 11, 77.Factors of 55: 1, 5, 11, 55.Factors of 154: 1, 2, 7, 11, 14, 22, 77, 154.GCF (77, 55, 154) = 11
1 + 2 + 100 + 55 = 158
Mean = average; so (77+10)/2 = 43.5 = mean of 77 plus 10.
There is a missing operator:If it is a plus: 77 + 2 = 79If it is a minus: 77 - 2 = 75If it is a times: 77 x 2 = 154If it is a divide: 77 / 2 = 381/2 = 38.5
2 + 77 + 899 + 7464867 + 784764 - 56788 + 5677 = 8,188,144
2 + 75 = 77
4/5 + 2/11 needs to have common denominators. In this case that is 55. 4/5 (11) + 2/11 (5) = 44/55 + 10/55 = 54/55.

75/60 or 1 and 15/60 or 1 and 1/4 Your choice :) wrong on all your answers 55 / 60 plus 2/3 = 95 over 60 55/60......=55 +2/3 of 60 =40 ............=95 your answer is 1 35/60 or broke down to it's LCD (lowest common denominator) 1 7/12
