Question

It is given that a:b=1:2 and b = 3c.Find a:b:c.

Please help me to solve this question with steps,thanks! orz ​

Answer 1

3 : 6 : 2

Explanation:

Given

b = 3c ( divide both sides by 3 )

c =
`(1)/(3)` b , that is

c =
`(1)/(3)` × 2 =
`(2)/(3)`

Thus

a : b : c = 1 : 2 :
`(2)/(3)` ( multiply all parts by 3 )

a : b : c = 3 : 6 : 2
