For this case we have the following fractions:

We must rewrite the fractions, using the same denominator.
We have then:
We multiply the first fraction by 11 in the numerator and denominator:

We multiply the second fraction by 2 in the numerator and denominator:

Rewriting we have:
For the first fraction:

For the second fraction:

We note that:

Answer:
The fractions are not equivalent:

So the ratio is 3:5. Se need to find x:1 you do that by dividing each side by 5. 3/5 = .6
