How To: Master adding and subtracting fractions

Master adding and subtracting fractions

To add two fractions we need to add the numerator and denominator. For example:

1/4+ 3/8=5/8. 3 is known as the numerator and 8 is called the denominator. Before adding fractions, first of all we need to take the LCM of the denominator and then divide the denominator with the LCM value and then multiply the numerator with the quotient. 3/9+7/9=10 /9. Let's add 1/16+ 1/3=? Take the LCM of 16 and 3. It will be 48. Now it will look like this: 3/48 + 16/48= 19/48.
