Question

How can complex fractions be used to solve problems involving ratios?

Answer 1

Explanation:

Answer 2

When you have ratios, and some unknowns, you can create complex fractions from them. Bring them to the same denominator, and solve for x.

Example - we have this proportion:
2-x
5-45
And we can change it into fraction:

`(2)/(5)=(x)/(45)`


`(2*9)/(5*9)=(x)/(45)`


`(18)/(45)=(x)/(45)`
18=x

In case of more complex fractions it may come in handy.
