Answer 2

a : c = 9 : 8

Explanation:

Expressing the ratios in fractional form , then

`(a)/(c)` =
`(a)/(b)` ×
`(b)/(c)`

Given a : b =
`(1)/(2)` :
`(1)/(3)` ( multiply both parts by 6 to clear the fractions )

a : b = 3 : 2 and b : c = 3 : 4 , then

`(a)/(c)` =
`(3)/(2)` ×
`(3)/(4)` =
`(3(3))/(2(4))` =
`(9)/(8)`

That is a : c = 9 : 8
