Comparing fractions using common denominators

Let's look at an example.
Compare.
start fraction, 3, divided by, 4, end fraction __ start fraction, 5, divided by, 10, end fraction
Let's change the fractions to have a common denominator of 20: (Want to review common denominators? Check out this article.)
Now that our fractions have the same denominator, we compare their numerators:
start color blueD, 15, end color blueD, is greater than, start color greenD, 10, end color greenD
start color blueD, start fraction, 15, divided by, 20, end fraction, end color blueD, is greater than, start color greenD, start fraction, 10, divided by, 20, end fraction, end color greenD
start color blueD, start fraction, 3, divided by, 4, end fraction, end color blueD, is greater than, start color greenD, start fraction, 5, divided by, 10, end fraction, end color greenD
