A fraction represents a part of a whole and is expressed as a ratio of two integers, where the numerator indicates how many parts are taken and the denominator indicates the total number of equal parts.

Front

How do you add fractions with different denominators?

Back

To add fractions with different denominators, first find a common denominator, convert each fraction to an equivalent fraction with that denominator, and then add the numerators while keeping the common denominator.

Front

What is the process for subtracting fractions?

Back

To subtract fractions, ensure they have a common denominator. Convert the fractions if necessary, subtract the numerators, and keep the common denominator.

Front

How do you convert a mixed number to an improper fraction?
