How do you find the sum of dissimilar fractions?

How do you find the sum of dissimilar fractions?

Sum of fractions with different denominators To add fractions with different denominators, the first thing that you have to do is find a common denominator: this is the least common multiple of the denominators that you have. Then we multiply each numerator by the number that we have multiplied the denominator by.

How do you add similar and dissimilar?

Multiply both parts of each fraction by the denominator of the other fraction, if the denominators are different. For example, if you are adding 1/3 and 2/5, multiply both 1 and 3 by 5, making the fraction 5/15. Then multiply both 2 and 5 by 3 (the denominator of the other fraction), making the fraction 6/15.

What is needed to change dissimilar fractions to similar fractions?

How to convert unlike fractions into similar fractions

• Find LCM (least common multiple) of the denominators.
• Convert the fractions to equivalent fractions with denominators equal to the LCM.

How do you add dissimilar fractions to similar fractions?

To add dissimilar fractions (fractions with different denominators), you must first convert the fractions so that the denominators are the same. Multiply both parts of each fraction by the denominator of the other fraction, if the denominators are different.

How do you add fractions with Unlike denominators?

To add fractions with unlike denominators, you will start by getting common denominators. Be sure to multiply the numerator by the same thing you multiply the denominator. Then add the numerators and keep the denominator the same.

What are the steps in adding fractions?

To add fractions there are Three Simple Steps: Step 1: Make sure the bottom numbers (the denominators) are the same Step 2: Add the top numbers (the numerators ), put that answer over the denominator Step 3: Simplify the fraction (if needed)

What is the rule for adding fractions?

To add fractions, the denominators must be the same. Use the lowest common multiple of each of the denominators, but whenever you multiply a denominator by a number, you must multiply the numerator by the same number.

How do you add three fractions together?

Answer and Explanation: Adding three fractions together is similar to adding two fractions: you can use the lowest common multiple (LCM) to find the common denominator for all the fractions. When you have fractions with the same denominator, you can add them up by adding the numerators together:
