Two ways: convert them to decimals or convert them to similar fractions and compare the numerators.
Treat the ratios as fractions. One way you can compare them is to convert them to decimal (divide the numerator by the denominator, or the first number of the ratio by the second number), then compare. Another way is to find a common denominator, then compare the numerators.
You draw each of the fractions on the number line, and see which one is more to the right, i.e., greater. Please note that plotting the exact position of fractions this way is a bit imprecise - it is more exact to convert the fractions to a common denominator.
To compare fractions which are not similar, the fractions must be made similar by putting them over a common denominator. There are two similar ways of doing this:Find the lowest common multiple of the denominators. Multiply the first numerator by whatever number you multiply the first denominator by to get that multiple, and do the same with the second numerator and denominator. You can then compare the numerators.Multiply the first numerator by the second denominator, and the second numerator by the first denominator, and put both numerators over the product of the two denominators. You can then compare the numerators.

I am not entirely sure what you mean, but if you need to add, subtract, or compare two fractions, they need to have the same denominator.
