Please help me on 1e.you have to simply the ratio and I’m really stuck.sos

Answer:
e) 5:1
Step-by-step explanation:
625 can be factored into 5*5*5*5 and 125 can be factored into 5*5*5
This means that we could look at the ratio as
5*5*5*5:5*5*5
We can then factor out (5*5*5) from each side to leave us with
5:1
