You can make equivalent fractions by multiplying the numerator and denominator of the given fraction by the same number k k 0. A common multiple of 2 and 3 is 6. First find the LCM of the two.

Steps for Adding Fractions with Unlike Denominators 1. Remember to reduce a fraction means to divide it by a common factor until the number one is the only number that can be evenly divided into both the numerator and denominator. 10 20 30 40 Multiples of 4.

When we do this our new fractions become ⁶₁₈ and ³₁₈. To add fractions there are Three Simple Steps. Check to see if you can simplify the fraction before you square it.

When it comes to adding and subtracting fractions its very simple once youve checked for or created if necessary a common denominator. If youre very lucky your denominators will already be the same so you just add together the numerators from the top halves and keep your existing denominator under the line. Find the GCM of the two denominators.

Addition and Subtraction with the. To multiply two fractions then simply multiply the numerators and multiply the denominators to get the product. You use equivalent fractions to make them the same.

To summarize the steps for adding fractions are. Find the LCM of the two denominators. How to Add Fractions.
