Answer 1

Ratio of Seniors to Juniors is 5:4

Ratio of Seniors to sophomores is 6:5

We'll make ratio of Seniors equal at both sides , So LCM of 5 and 6 is 30.

Ratio of senior to Juniors = 5/4 × 6/6 = 30/24

Ratio of Seniors to Sophomores = 6/5 × 5/5 = 30/25

So, Ratio of Sophomores to Juniors = 25:24
