How do you add and subtract dissimilar fractions with whole numbers?

How do you add and subtract dissimilar fractions with whole numbers?

Step 1: Find the Lowest Common Multiple (LCM) between the denominators. Step 2: Multiply the numerator and denominator of each fraction by a number so that they have the LCM as their new denominator. Step 3: Add or subtract the numerators and keep the denominator the same.

How do you add fractions and whole numbers?

Answer: To add a fraction to a whole number, convert the whole number into a fraction, form a common denominator, and then add the two numerators.

What are the rules in adding and subtracting dissimilar fractions?

To add or subtract fractions they must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.

How do you subtract fractions with whole numbers?

When subtracting fractions from whole numbers, change the whole number into a fraction, then form a common denominator and subtract the two numerators.

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:
