Question

If


`(f)/(g) = (1)/(4)`
and

`(g)/(h ) = (2)/(5)`
what is the ratio of f:h​

Answer 1

f:h = 1 : 10

Explanation:

`(f)/(g)=(1)/(4)\\\\Cross multiply,\\\\4f = g\\\\g = 4f ------------(I)\\\\(g)/(h)=(2)/(5)\\\\(4f)/(h)=(2)/(5) from(I)\\\\(f)/(h)=(2)/(5*4)\\\\(f)/(h)=(1)/(5*2)\\\\(f)/(h)=(1)/(10)`
