Students will be required to find common denominators in order to add the fractions. What if the fractions do not have the same denominator. After doing all 12 problems students should be more comfortable doing these problems and have a clear understanding of how to solve.

720 035 Now move the decimal points to convert them into 35. Here youll learn the easy way then a quick trick that works in a few special cases and finally the traditional way. Make equivalent fractions using the LCD.

Each page contains 6 problems. Subtracting fractions with different denominators. The denominators should now be the same.

The following procedure summarizes the steps we used in examples 1 through 4. Now we are going to solve a problem that is a bit more difficult because the denominators are different prime numbers and we need to go through the process a bit more carefully. Steps for Adding Fractions with Unlike Denominators.

Compare two fractions with different numerators and different denominators eg by creating common denominators or numerators or by comparing to a benchmark fraction such as 12. Youll need to multiply the entire fraction to make. Multiply the numerator and denominator to get like denominators.

Make equivalent fractions with the new denominator. Turn the other. You will notice that your problem has unlike denominators meaning the bottom numbers are different from each other.
