Let’s solve each problem one by one. Remember: when adding or subtracting fractions with the same denominator, you just add or subtract the numerators and keep the denominator the same.

1.
$\frac{1}{5} + \frac{3}{5} = \frac{1+3}{5} = \frac{4}{5}$
2.
$\frac{2}{3} - \frac{1}{3} = \frac{2-1}{3} = \frac{1}{3}$
3.
$\frac{6}{12} - \frac{5}{12} = \frac{6-5}{12} = \frac{1}{12}$
4.
$\frac{7}{16} - \frac{3}{16} = \frac{7-3}{16} = \frac{4}{16}$ → Simplify: divide numerator and denominator by 4 → $\frac{1}{4}$
5.
$\frac{8}{10} - \frac{2}{10} = \frac{8-2}{10} = \frac{6}{10}$ → Simplify: divide by 2 → $\frac{3}{5}$
6.
$\frac{5}{8} - \frac{1}{8} = \frac{5-1}{8} = \frac{4}{8}$ → Simplify: divide by 4 → $\frac{1}{2}$
7.
$\frac{6}{9} - \frac{5}{9} = \frac{6-5}{9} = \frac{1}{9}$
8.
$\frac{4}{16} + \frac{4}{16} = \frac{4+4}{16} = \frac{8}{16}$ → Simplify: divide by 8 → $\frac{1}{2}$
9.
$\frac{3}{7} + \frac{1}{7} = \frac{3+1}{7} = \frac{4}{7}$
10.
$\frac{10}{12} - \frac{6}{12} = \frac{10-6}{12} = \frac{4}{12}$ → Simplify: divide by 4 → $\frac{1}{3}$
11.
$\frac{4}{6} + \frac{1}{6} = \frac{4+1}{6} = \frac{5}{6}$
12.
$\frac{7}{8} - \frac{2}{8} = \frac{7-2}{8} = \frac{5}{8}$
13.
$\frac{6}{12} - \frac{3}{12} = \frac{6-3}{12} = \frac{3}{12}$ → Simplify: divide by 3 → $\frac{1}{4}$
14.
$\frac{2}{8} + \frac{3}{8} = \frac{2+3}{8} = \frac{5}{8}$
15.
$\frac{5}{9} - \frac{3}{9} = \frac{5-3}{9} = \frac{2}{9}$
16.
$\frac{5}{18} + \frac{4}{18} = \frac{5+4}{18} = \frac{9}{18}$ → Simplify: divide by 9 → $\frac{1}{2}$
