achal14: can you please give me the process

Umeshlohani: yes

Umeshlohani: make b common in both

Umeshlohani: by multiplication

63:525:85

Step-by-step explanation:

Given :-

a:b = 3:25

b:c = 105:17

we can also write ----

a/b = 3/25 , b/c = 105/17

Now to find a:b:c , first we have to do LCM of the numbers present at b

So the numbers present at b are 25 and 105

LCM OF 25 AND 105 IS 525

Then 525 ÷ 25 = 21

525 ÷ 105 = 5

Now we get 3×21/25×21 = 63/525 and

105×5/17×5 = 525/85

Therefore a:b:c = 63:525:85 (Ans)
