How to Add and Subtract Fractions?

There must be a common denominator between the fractions in order to add or subtract them. A number which is a multiple of both denominators is referred to as the common denominator.

When adding fractions with the same denominator, add the numerators while maintaining the original denominator. When we add 1/4 and 1/4, for instance, we get (1+1)/4 = 2/4 = 1/2.

Subtract the numerators while maintaining the same denominator to subtract fractions with a common denominator.

• Write your equation down. Put the same number once as the denominator for your answer if the denominators of the two fractions you are adding or subtracting are the same. 

In other words, it’s not required to write 1/5 + 2/5 = when combining 1/5 and 2/5. The formula is: 1+2/5 =? Given that the denominator is the same, there can only be one writing. The two numerators are then arranged.

• Combine the numerators. Any fraction’s largest number is known as the “numerator.” The numerators in the example above, 1/5 and 2/5, are 1 and 2.

No matter how you spell it—1/5 + 2/5 or 1+2/5—the answer is always 3! In the end, 1 + 2 = 3.

• The denominator should be ignored. Don’t use it since you are only using one constant denominator! Don’t multiply, divide, add, or subtract. Simply let things be. 

Using the same example, this means that 5 is our denominator. I’m done now! Our fraction’s bottom number is that. Already half the solution is there!

• Create your response. You just need to type out your numerator and denominator at this point. The solution to this problem is 3/5 if you’ve followed the example above.

Which number was your numerator? The common denominator? 5. As a result, 1 + 2 + 5, or 1 + 2 + 5, equals 3
