## Steps in subtraction of fractions

• Convert mixed to improper fraction.
• Find their LCM.
• Divide the LCM by the denominator.
• Multiply by the numerator.
• Subtract the numerators.
• Reduce to its lowest form.

Let’s take an example.

## Sample question

3\frac{2}{3}\frac{1}{6}

### 1. Convert the mixed fraction to improper fraction

3\frac{2}{3} (mixed fraction)

= \dfrac{11}{3} (improper fraction)

Therefore…

\dfrac{11}{3}\dfrac{1}{6}

### 2. Find the LCM of the denominators

The LCM of 3 and 6

= 6

\dfrac{}{6}

6 ÷ 3 = 2

6 ÷ 6 = 1

2 × 11 = 22

1 × 1 = 1

\dfrac{22-1}{6}

\dfrac{22-1}{6}

= \dfrac{21}{6}

\dfrac{21}{6}

= \dfrac{7}{2}
