Steps to add 2/7 and 3/8
Only parts of the same size can be counted together, so 2/7 + 3/8 is solved by giving both fractions the same denominator and then adding the numerators. Here is every step.
Step 1: Find the common denominator
The least common multiple of 7 and 8 is 56, so both fractions are rewritten over it.

3/8 = 21/56 (× 7)
Step 2: Add the numerators
The denominator stays as it is — it says how big each part is, and that has not changed. Only the count of parts is added up.
16/56 + 21/56
=(16 + 21)/56
=37/56

Adding Fractions Calculator
This calculator adds two fractions and shows the whole solution, not just the answer. Mixed numbers and whole numbers are accepted on both sides, so you can add 2 1/3 to 1 just as easily as 1/2 to 1/3.
For example, it can help you find out what is 2/7 plus 3/8? (The answer is: 37/56).
Enter the first fraction on the left and the second one on the right (for example '2/7' and '3/8'), then press the button.
The result is given as a fraction in its lowest terms, as a mixed number when it is greater than one, and as a decimal — with an approximation sign whenever the decimal never ends.
Every page also shows why the method works: only parts of the same size can be counted together, so both fractions are first rewritten over their least common denominator and only then are the numerators added.
