Here I have a video that can answer your question

Here's the solution,
a : b = 4 : 5
b : c = 3 : 5
now, we can combine the ratios if the value of b is equal in both of them, and we have to make sure it's the minimum value since we have to obtain it in the simplest form, so let's take the L.C.M of b in both proportions .
L.C.M of b in both ratios is 15
so
ratio 1.)
- a : b = 4 : 5
- a : b = 12 : 15
( just multiplied both numbers by 3 to make b = 15 )
ratio 2.)
- b : c = 3 : 5
- b : c = 15 : 25
( just multiplied both numbers by 5 to make b = 15)
now, simply combine the equations to get,
a : b : c = 12 : 15 : 25
and hence,
a : c = 12 : 25
