Follow the full solution, then compare it with the other examples linked below.

easy

Compute

\frac{5}{6} - \frac{1}{4}

1
LCD of $6$ and $4$ : $\text{LCD} = 12$ . Convert: $\frac{5}{6} = \frac{10}{12}$ and $\frac{1}{4} = \frac{3}{12}$ .
2
Subtract: $\frac{10}{12} - \frac{3}{12} = \frac{7}{12}$ .

Answer

\frac{7}{12}

Use the LCD to create equal-sized pieces, then subtract only the numerators. Always verify that the final fraction is fully simplified.
