56:48 = 7:6
65:35 = 13:7
7/6 and 13/7
LCM of 6 and 7 is 42
so
(7*7)/(6*6) and (13*6)/(7*6)
49/42 and 78/42
78/42 > 49/42
Therefore 13/7 is greater
⇒ 65:35 is the right answer
65:35 = 13:7

56 : 48 = 56 / 48
= 8 × 7 / 8 × 6
= 7/6
65 : 35 = 65 / 35
= 5 × 13 / 5 × 7
= 13/7
We compare in 7/6 & 13/7
7/6 = 7 × 7 / 7 × 6
= 49 / 42
13 / 7 = 13 × 6 / 7 × 6
= 78 / 42
49 < 78
7 / 6 < 13 / 7
so
56 ; 48 < 65 : 35
= 8 × 7 / 8 × 6
= 7/6
65 : 35 = 65 / 35
= 5 × 13 / 5 × 7
= 13/7
We compare in 7/6 & 13/7
7/6 = 7 × 7 / 7 × 6
= 49 / 42
13 / 7 = 13 × 6 / 7 × 6
= 78 / 42
49 < 78
7 / 6 < 13 / 7
so
56 ; 48 < 65 : 35
