15 + 35 = 5*(3 + 7).
The factors of 25 are: 1, 5, 25 The factors of 35 are: 1, 5, 7, 35
Factors for 35 are: 1, 5, 7 and 35. The factor pairs are: 1 X 35 5 X 7
The factors of 35 are: 1, 5, 7, 35.
(30,1)(15,2)(10,3)(6,5) (35,1)(7,5)
546 = 7*78 and 35 = 7*5 so 546/35 = 78/5
5/13 + 6/7 = 35/91 + 78/91 = 1 and 22/91
(7a + 35)/-7 = 7(a + 5)/-7 = -(a + 5) = (-a - 5)
The LCM for 35 and 78 is 2,730. ---------------------------------------------------------------------------------- 35 = 5 x 7 78 = 2 x 3 x 13 LCM = s x 7 x 2 x 3 x 13 = 35 x 78 = 2730
(7h + 35) / (-7) = (7h)/(-7) + (35)/(-7) = (-h) + (-5) = - (h + 5)
5/7 +4/5 = 25/35 + 28/35 = 53/35
35
6/7 + 7/5 = 30/35 + 49/35 = 79/35 = 2 and 9/35
2/7 = 10/35 1/5 = 7/35 10/35 + 7/35 = 17/35
78/5. divide both by 7
2/5 + 6/7 = (2×7)/(5×7) + (6×5)/(7×5) = 14/35 + 30/35 = (14+30)/35 = 44/35 = (35+9)/35 = 1 9/35
2/5 + 2/7 = 24/35 2/5 + 2/7 =(2/5 * 7/7) + (2/7 * 5/5) =14/35 + 10/35 =24/35
