When comparing two fractions with same denominator, the larger fraction is the one with the greater numerator.

Let's illustrate through an example.

Example 1

The denominator of both the fractions is same i.e. 6.

To compare fractions when the denominators of two fractions are the same, the one with the greater numerator is larger.
So, your sister has more cake than you.
To compare fractions with different denominators, we must convert the fractions to equivalent fractions with a common denominator and then look for numerators.

Example 2

Convert these fractions to equivalent fractions with a common denominator in order to compare them.

Follow these steps:

List out the multiples.

The smallest multiple the two denominators have in common is 6.
The least common denominator (LCD) of the fractions is the least common multiple of their denominators. Now, convert these fractions to equivalent fractions with a denominator 6. As we can notice the first fraction already has the denominator 6.
So, convert the other fraction with denominator 6.

Let's look for numerators to compare.

We know, 4 is greater than 3.

If the denominator is the same, look at the numerators, and put the fractions in order.

If the denominator is different, we need to convert our fractions to equivalent fractions of the same denominator and then compare them to put in order.

Example 3

Here the denominator of all the fractions is same so we look at the numerators.

1 is the smallest number, followed by 7, 9, and 12.

1 < 7 < 9 < 12

Arrange the fractions from least to greatest:

Example 4

These fractions have unlike fractions. We will use the least common denominator (LCD) to write these fractions as equivalents fractions with same denominators, and then compare.

We know,

6 < 8 < 9 < 10

So,

Switch fractions back to their original form:
