To compare fractions, you can compare the numerators or denominators, or make the denominators the same using equivalent fractions: 

• Compare the numerators
  When the denominators are the same, the fraction with the larger numerator is larger. For example, 9/12 is greater than 4/12 because 9 is larger than 4. 

• Compare the denominators
  When the numerators are the same, the fraction with the smaller denominator is larger. 

• Make the denominators the same
  When the denominators are different, you can make them the same by finding the least common multiple (LCM) of the denominators and converting each fraction to an equivalent fraction with the denominator equal to the LCM. Then, compare the numerators of the equivalent fractions.

Comparing fractions involves determining which fraction is larger or smaller. To compare fractions, you need to compare their numerators (the numbers on top) and denominators (the numbers on the bottom). If the denominators are the same, the fraction with the larger numerator is larger. If the numerators are the same, the fraction with the smaller denominator is larger. You can also compare fractions by converting them to equivalent decimals or percents. Additionally, you can use visual aids like number lines or area models to help compare fractions. This can make the comparison process more intuitive and easier to understand.
