Back

Two fractions are equivalent if they represent the same part of a whole, even if they have different numerators and denominators. For example, 1/2 and 2/4 are equivalent fractions.

Front

How do you compare two fractions with different denominators?

Back

To compare fractions with different denominators, convert them to equivalent fractions with a common denominator, then compare the numerators.

Front

What is the process to add fractions with the same denominator?

Back

To add fractions with the same denominator, simply add the numerators and keep the denominator the same. For example, 1/4 + 2/4 = (1+2)/4 = 3/4.

Front

How do you subtract fractions with the same denominator?

Back

To subtract fractions with the same denominator, subtract the numerators and keep the denominator the same. For example, 3/5 - 1/5 = (3-1)/5 = 2/5.
