5/35 = 1/7
5/7 +4/5 = 25/35 + 28/35 = 53/35
What can 5 and 7 go into together? 35! So then it would be 14 over 35 and 5 over 35. I got the 14 from multiplying 7 to both the top and bottom of 2 over 5, so it would be: 2 x 7= 14, 1 x 5= 5 5 x 7= 35 and 7 x 5= 35 so 14 over 35 and 5 over 35.
35/5 = 7
5 over 7 is greater than 3 over five. You have to find a common denominator. The common denominator is 35 so 5 over 7 would become 25 over 35 and 3 over 5 would become 21 over 35. 25/35 > 21/35 = 5/7 > 3/5
divide both by 5 35/5 = 7 110/5 = 22 35/110 = 7/22
5/35 = 1/7
5:7 (or 5/7) is equivalent to 10:14 (10/14) and 15:21 (15/21).
The common denominator here is 35. 3/5+5/7 is 21/35+25/35. This is 46/35 or 1 and 11/35.
(42/5)/(35/9)=(42/5)x(9/35)=378/175
(35/8) / (36/5) = (35/8) x (5/36) = 175/288
175/35 = 35/7= 5
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
