Steps in addition of fractions
- Convert mixed to improper fraction.
- Find their LCM.
- Divide the LCM by the denominator.
- Multiply by the numerator.
- Add the numerators.
- Reduce to its lowest form.
Sample question
Let’s take an example.
2\frac{1}{3} + \frac{10}{4}
1. Convert the mixed fraction to improper fraction
2\frac{1}{3} (mixed fraction)
= \dfrac{7}{3} (improper fraction)
Therefore…
\dfrac{7}{3} + \dfrac{10}{4}
2. Find the LCM of the denominators
The LCM of 3 and 4
= 12
3. Write the LCM as your new denominator
\dfrac{}{12}
4. Divide the LCM by each denominator
12 ÷ 3 = 4
12 ÷ 4 = 3
5. Multiply the answer by their numerator
4 × 7 = 28
3 × 10 = 30
6. Write the answers as new numerators
\dfrac{28+30}{12}
7. Add the new numerators
\dfrac{28+30}{12}
= \dfrac{58}{12}
8. Reduce to its lowest form
\dfrac{58}{12}
= \dfrac{29}{6}
