Question. 97

Subtract \(\dfrac{1}{6}\) from \(\dfrac{1}{2}\).

Answer:

\(\dfrac{1}{3}\)

Detailed Answer with Explanation:

We want to find: \(\dfrac{1}{2} - \dfrac{1}{6}\).

  1. Make the denominators the same.
    The smallest number that both 2 and 6 divide into is 6 (this is the LCM).

  2. Change \(\dfrac{1}{2}\) to sixths.
    Multiply top and bottom by 3:

    \[ \dfrac{1}{2} \times \dfrac{3}{3} = \dfrac{3}{6} \]

  3. Now subtract the fractions.
    Keep the denominator 6 and subtract the numerators:

    \[ \dfrac{3}{6} - \dfrac{1}{6} = \dfrac{2}{6} \]

  4. Simplify the answer.
    Divide top and bottom by 2:

    \[ \dfrac{2}{6} = \dfrac{1}{3} \]

Final Answer: \(\dfrac{1}{3}\).
