Zadaci za vežbanje

1. Reši jednačine:

x + \frac{1}{4} = \frac{2}{5}

x + \frac{1}{5} = \frac{3}{4}

x – \frac{2}{3} = \frac{1}{6}

\frac{2}{5} – x = \frac{1}{3}

\frac{2}{9} – x = \frac{3}{7}

2. Reši jednačine:

x + \frac{3}{4} = \frac{8}{9}

\frac{3}{4} – x = \frac{1}{3}

x + \frac{2}{3} = \frac{7}{11}

\frac{5}{7} – x = \frac{2}{5}

x – \frac{1}{3} = \frac{1}{5}

3. Reši jednačine:

x – \frac{4}{7} = \frac{3}{8}

x + \frac{1}{5} = \frac{4}{9}

\frac{3}{8} – x = \frac{1}{4}

\frac{2}{5} – x = \frac{1}{6}

\frac{3}{8} + x = \frac{4}{5}

4. Reši jednačine:

\frac{2}{5} + x = \frac{6}{11}

\frac{1}{2} + x = \frac{7}{9}

\frac{3}{4} – x = \frac{2}{7}

\frac{2}{3} – x = \frac{1}{6}

\frac{4}{7} – x = \frac{1}{9}

5. Reši jednačine:

\frac{11}{13} – x = \frac{1}{4}

\frac{5}{7} – x = \frac{1}{5}

\frac{3}{8} + x = \frac{2}{7}

\frac{5}{6} + x = \frac{1}{3}

\frac{4}{9} – x = \frac{2}{5}

6. Reši jednačine:

\frac{1}{5} – x = \frac{1}{8}

\frac{3}{2} + x = \frac{7}{3}

\frac{6}{5} + x = \frac{4}{3}

\frac{1}{4} + x = \frac{5}{3}

x – \frac{2}{7} = \frac{7}{6}
