If g : h = 8 : 9 and h : i = 9 : 12, then find g : h : i?

17 : 9 : 21

8 : 8 : 12

8 : 9 : 12

None of these

Given:

g : h = 8 : 9

h : i = 9 : 12

To find the combined ratio g : h : i, we need to make the ratio of h the same in both.

g : h = 8 : 9

h : i = 9 : 12

Since h has the same ratio in both (9), we can directly combine:

g : h : i = 8 : 9 : 12
