Here are the solutions for the subtraction of fractions problems. Since all the fractions in each problem have the same bottom number (denominator), we only need to subtract the top numbers (numerators). The bottom number stays the same.
Step-by-step Solutions:
1.
$\frac{5}{6} - \frac{4}{6}$
* Subtract the tops: $5 - 4 = 1$
* Keep the bottom: $6$
* Result: $\frac{1}{6}$
2.
$\frac{4}{5} - \frac{2}{5}$
* Subtract the tops: $4 - 2 = 2$
* Keep the bottom: $5$
* Result: $\frac{2}{5}$
3.
$\frac{6}{7} - \frac{1}{7}$
* Subtract the tops: $6 - 1 = 5$
* Keep the bottom: $7$
* Result: $\frac{5}{7}$
4.
$\frac{5}{9} - \frac{2}{9}$
* Subtract the tops: $5 - 2 = 3$
* Keep the bottom: $9$
* Result: $\frac{3}{9}$ (This can be simplified to $\frac{1}{3}$, but $\frac{3}{9}$ is the direct answer)
5.
$\frac{6}{8} - \frac{2}{8} - \frac{1}{8}$
* Subtract the tops in order: $6 - 2 = 4$, then $4 - 1 = 3$
* Keep the bottom: $8$
* Result: $\frac{3}{8}$
6.
$\frac{6}{7} - \frac{4}{7} - \frac{1}{7}$
* Subtract the tops in order: $6 - 4 = 2$, then $2 - 1 = 1$
* Keep the bottom: $7$
* Result: $\frac{1}{7}$
7.
$\frac{5}{6} - \frac{1}{6} - \frac{2}{6}$
* Subtract the tops in order: $5 - 1 = 4$, then $4 - 2 = 2$
* Keep the bottom: $6$
* Result: $\frac{2}{6}$ (This can be simplified to $\frac{1}{3}$)
8.
$\frac{7}{9} - \frac{1}{9} - \frac{4}{9}$
* Subtract the tops in order: $7 - 1 = 6$, then $6 - 4 = 2$
* Keep the bottom: $9$
* Result: $\frac{2}{9}$
9.
$\frac{4}{5} - \frac{1}{5} - \frac{1}{5}$
* Subtract the tops in order: $4 - 1 = 3$, then $3 - 1 = 2$
* Keep the bottom: $5$
* Result: $\frac{2}{5}$
10.
$\frac{6}{7} - \frac{2}{7} - \frac{2}{7}$
* Subtract the tops in order: $6 - 2 = 4$, then $4 - 2 = 2$
* Keep the bottom: $7$
* Result: $\frac{2}{7}$
Final Answer:
1) $\frac{1}{6}$
2) $\frac{2}{5}$
3) $\frac{5}{7}$
4) $\frac{3}{9}$ (or $\frac{1}{3}$)
5) $\frac{3}{8}$
6) $\frac{1}{7}$
7) $\frac{2}{6}$ (or $\frac{1}{3}$)
8) $\frac{2}{9}$
9) $\frac{2}{5}$
10) $\frac{2}{7}$
