ADDING & MULTIPLYING FRACTIONS

Shown below are examples of adding, and multiplying fractions. Please follow the step by step instructions to learn how to add or multiply fractions.

ADDING FRACTIONS:

In order to add fractions the denominators of all the fractions being added must be the same. If the denominators of the fractions to be added are not the same, then the LCD (Least Common Denominator) must be found, and the numerators have to be multiplied by the appropriate numbers.

Example 1- Add the following fractions:

EDUCATIONAL LINKS

The top number of a fraction is called a numerator, and the bottom of the fraction is called a denominator.

For your conveniance the numerators have been colored in red, and the denominators have been colored in blue.

PLEASE NOTE

Directions:

1. Find the LCD of the two fractions. In other words find the least common products of 4, and 5. In this case our LCD is 20, because 20 is the least common product of both 4, and 5. LCD

2. After finding the LCD figure out what you need to multiply the original denominator with to come up with the LCD. Since our LCD is 20 we know that we have to multiply the first denominator, by 5. Since we multiplied the denominator of the first fraction with 5 we must also multiply the numerator with 5 as well. Similiarly we multiply 3 with the numerator, and denominator of the second fraction as well.

3. After multiplying the appropriate numbers, simplify the fractions as neccessary.

4. Your final answer should come out to be 14/20 or 7/10. If you didn't get the correct answer refer to following breakdown of steps below:

MULTIPLYING FRACTIONS:

Multiplying fractions is quite simple. To multiply two or mor fractions simply multiply all the numerators with one another, and do the same for all of the denominators.

Example 2- Multiply the following fractions:

Directions:

1.Multiply all of the numerator together, and that value will be the numerator of your answer.

2.Multiply all of the denominators across, and that value will be the denominator of your answer.

3. Your final answer should come out to be 3/20. If you didn't get the correct answer please refer to the breakdown of steps shown below:
