Steps to Solve Fraction Addition

To solve any two fraction additions, follow these steps:

1. Multiply the whole number by the denominator of the fraction.

2. Add the result to the numerator of the fraction.

3. Write the sum as the numerator of the improper fraction, and keep the denominator the same.

4. Simplify the fraction, if possible.

Worked Example of Fraction Additions

Example 1: Add 1/4 + 2/4.

• Step 1: The denominators are already the same.

• Step 2: 1 + 2 = 3.

• Step 3: The sum is 3/4.

Example 2: Add 3/5 + 1/10.

• Step 1: Convert the fractions to have the same denominator. The LCM of 5 and 10 is 10.
  3/5 becomes 6/10, and 1/10 remains the same.

• Step 2: 6 + 1 = 7.

• Step 3: The sum is 7/10.

Example 3: Add 2/3 + 1/6.

• Step 1: Convert the fractions to have the same denominator. The LCM of 3 and 6 is 6.
  2/3 becomes 4/6, and 1/6 remains the same.

• Step 2: 4 + 1 = 5.

• Step 3: The sum is 5/6.

Steps to Solve Fraction Subtraction

1. Make sure the denominators of the fractions are the same. If they’re not, find the least common multiple (LCM) of the denominators and convert the fractions to have the same denominator.

2. Subtract the numerator of the second fraction from the numerator of the first fraction.

3. Keep the denominator the same.

4. Simplify the fraction, if possible.

Example: Subtract 3/4 – 1/4.

• Step 1: The denominators are already the same.

• Step 2: 3 – 1 = 2.

• Step 3: The difference is 2/4.
