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:
You can compare similar fractions by looking at their numerators. You can compare dissimilar fractions by converting them to similar fractions and looking at their numerators. You can convert a dissimilar fraction to a similar fraction by finding the least common denominator.
Two ways: convert them to decimals or convert them to similar fractions and compare the numerators.
Two ways: Convert them to decimals and compare or convert them to equivalent fractions with a common denominator and compare the numerators.
I assume you mean, with different denominators. If you want to add the fractions, subtract them, or compare them (determine which one is greater), you have to convert them to similar fractions (fractions with the same denominator) first. Converting to similar fractions is not necessary, and usually doesn't even help, if you want to multiply or divide fractions.
Similar fractions are fractions with the same denominators.
to change dessimilar fractions to similar fractions you divide
you compare them
You can either convert fractions to decimals and compare the decimal numbers; find equivalent fractions with the same denominator and then compare numerators or find equivalent fractions with the same numerator and then compare denominators.
Similar fractions are those denominators the same.

The same way as proper fractions. Make sure the denominators are the same. If they're not, convert them to equivalent fractions with similar denominators. Then you can see which numerator is greater.
You cannot compare fractions by using the GCF since GCF determines the common factors of both fractions. Instead, use the LCD to compare the fractions. Find the LCM of the denominator terms of the fractions. Then, obtain the fractions with the common denominators. Finally, compare the numerator values to determine which fraction is the greatest/least.
