Answer 1

$\LARGE\tt{} \dfrac{7}{12} + \dfrac{5}{6} + \dfrac{1}{3} \\ \\ \LARGE\tt{} \dfrac{7}{12} + \dfrac{5 \times 2}{6 \times 2} + \frac{1 \times 4}{3 \times 4} \\ \\\LARGE\tt{} \dfrac{7}{12} + \dfrac{10}{12} + \dfrac{4}{12} \\ \\ \LARGE\tt{} \dfrac{7 + 10 + 4}{12} \\ \\ \LARGE\tt{} \dfrac{21}{12} \\ \\ \LARGE\tt{} \dfrac{21 \div 3}{12 \div 3} \\ \\ \LARGE\tt{} \boxed{ \dfrac{7}{4} }$
