Answer 1

1.

$\frac{1}{2} + \frac{1}{3} + \frac{1}{4} + \frac{1}{5} = \frac{77}{60}$

2.

$\frac{5}{6} + \frac{1}{3} - \frac{6}{16} - \frac{5}{12} = \frac{3}{8}$

3.

$\frac{4}{5} + \frac{3}{7} = \frac{43}{35}$

4.

$\frac{4}{6} + \frac{3}{9} - \frac{1}{12} = \frac{11}{12}$

5.

$\frac{5}{12} + \frac{6}{8} - \frac{1}{2} + \frac{2}{3} = \frac{4}{3}$

6.

$\frac{4}{11} + \frac{3}{22} - \frac{1}{44} = \frac{21}{44}$

7.

$24 - \frac{4}{15} - \frac{1}{5} = \frac{353}{15}$

8.

$\frac{2}{4} + \frac{29}{36} - \frac{7}{12} = \frac{13}{18}$

9.

$\frac{7}{8} - \frac{2}{5} + \frac{1}{2} - \frac{9}{20} = \frac{21}{40}$

10.

$\frac{2}{3} - \frac{4}{9} - \frac{6}{27} + \frac{11}{36} = \frac{11}{36}$
