For this case we convert the mixed numbers into fractions:


7 \frac {5} {6} = \frac {6 * 7 + 5} {6} = \frac {42 + 5} {6} = \frac {47} {6}\\3 \frac {1} {12} = \frac {12 * 3 + 1} {12} = \frac {36 + 1} {12} = \frac {37} {12}

Rewriting the expression:


\frac {47} {6} - \frac {37} {12} =\\\frac {12 * 47-6 * 37} {6 * 12} =\\\frac {564-222} {72} =\\\frac {342} {72} =

We simplify:


\frac {171} {36} =\\\frac {57} {12} =\\\frac {19} {4}

Thus, the simplified form is:
\frac {19} {4}

Answer:


\frac {19} {4}
