التصحيح
عمليات الضرب:
\[\frac{4}{5} \times \frac{1}{8} = \frac{4 \times 1}{5 \times 8} = \frac{4}{40} = \frac{1}{10}\]
\[\frac{5}{6} \times \frac{12}{25} = \frac{5 \times 12}{6 \times 25} = \frac{60}{150} = \frac{2}{5}\]
\[\frac{3}{7} \times \frac{4}{6} = \frac{3 \times 4}{7 \times 6} = \frac{12}{42} = \frac{2}{7}\]
عمليات الجمع:
\[\frac{5}{6} + \frac{7}{3} = \frac{5}{6} + \frac{14}{6} = \frac{19}{6}\]
\[2 + \frac{3}{4} = \frac{8}{4} + \frac{3}{4} = \frac{11}{4}\]
\[2 + \frac{1}{3} = \frac{6}{3} + \frac{1}{3} = \frac{7}{3}\]
عمليات الطرح:
\[1 - \frac{2}{5} = \frac{5}{5} - \frac{2}{5} = \frac{3}{5}\]
\[\frac{13}{4} - 3 = \frac{13}{4} - \frac{12}{4} = \frac{1}{4}\]
\[\frac{4}{5} - \frac{3}{7} = \frac{28}{35} - \frac{15}{35} = \frac{13}{35}\]
\[1 - \frac{5}{6} = \frac{6}{6} - \frac{5}{6} = \frac{1}{6}\]
\[\frac{6}{5} - 1 = \frac{6}{5} - \frac{5}{5} = \frac{1}{5}\]
\[2 - \frac{3}{4} = \frac{8}{4} - \frac{3}{4} = \frac{5}{4}\]
الأجوبة: \[\frac{1}{10}\]، \[\frac{2}{5}\]، \[\frac{2}{7}\]، \[\frac{19}{6}\]، \[\frac{3}{5}\]، \[\frac{11}{4}\]، \[\frac{1}{4}\]، \[\frac{7}{3}\]، \[\frac{13}{35}\]، \[\frac{1}{6}\]، \[\frac{1}{5}\]، \[\frac{5}{4}\]
