**24cm, 36cm, and 60cm**

**Step-by-step explanation:**

2 + 3 + 5 = 10 we see there are 10 parts of all of the ratios that make up 120 that means we can divide this to get 12 as each part.

2 parts = 2 * 12 = 24

3 parts = 3 * 12 = 36

5 parts = 5 * 12 = 60

Check: 24cm + 36cm + 60cm = 120cm

Sorry if its unclear, I tried my best
