Question

Write a proportion. 1 2- is to 19 as 1-is to 17 9 9 29

Answer 1

The proportion is 1/9.

Explanation:

Converting the mixed numbers to fraction:

`2(1)/(9)=(2\ast9+1)/(9)=(19)/(9)`
`1(8)/(9)=(9\ast1+8)/(9)=(17)/(9)`

Proportion:

19/9 is to 19 as 17/9 is to 17

To find the proportion, we solve one of these divisions. So

`((19)/(9))/(19)=(19)/(9)\ast(1)/(19)=(1)/(9)`

The proportion is 1/9.
