a2 + 28a + 27 = 0 (a + 1)(a + 27) = 0 a = -1 or -27 However, the second line is the factorised form, the third is what a is equal to
76. 50 plus 27 is 77, and then subtract 1 (50-49) and you get 76.
10/270 + 15/270 + 27/270 = 52/270 = 26/135
86 + 48 = 134 25/27 + 11/27 = 36/27 or 1 and 1/3 134 + 1 and 1/3 = 135 and 1/3
