Question

Subtracting $\frac{1}{6}$ from $\frac{1}{8}$ leaves ______.

• A. $\frac{-7}{24}$
• B. $\frac{7}{24}$
• C. $\frac{-1}{24}$
• D. $\frac{1}{24}$

Answer 1

The correct option is C

$\frac{-1}{24}$

Subtracting $\frac{1}{6}$ from $\frac{1}{8}$
= $\frac{1}{8}-\frac{1}{6}$

LCM of 8 and 6 is 24

= $\frac{1\times 3}{8\times 3}-\frac{1\times 4}{6\times 4}$

= $\frac{3-4}{24}$

= $\frac{-1}{24}$
