1-94.

Rewrite each expression as a single fraction. Homework Help ✎

  1. You cannot add or subtract fractions with different denominators. To make it possible to subtract, find the lowest common multiple of the two denominators.

    The LCM of 8 and 6 is 24.

    This will make the denominators the same.

    Now you can subtract the numerator of the first term from the numerator of the second.

  2. You don't need to change the denominator for this one. However, you will end up with a fraction greater than 1. You will need to change it to a mixed number.

  3. This problem can be solved in the same way as part (a).
