(a) $\frac{3}{4}$
(b) $\frac{-3}{4}$
(c) $\frac{-7}{12}$
(d) $\frac{7}{12}$

Answer 1

$\begin{array}{l}\\ \left(\text{a}\right)\frac{3}{4}\\ \frac{5}{4}-\frac{7}{6}-\frac{(-2)}{3}\\ \mathrm{L}.\mathrm{C}.\mathrm{M}.\mathrm{of}4,6\mathrm{and}3\mathrm{is}12.\\ \begin{array}{l}=\frac{15-14+8}{12}\\ =\frac{23-14}{12}\\ =\frac{{\sout{9}}^3}{\sout{1}{\sout{2}}_4}=\frac{3}{4}\end{array}\\ \end{array}$
