A= [tex]-\frac{3}{5} +\frac{1}{10}[/tex]× [tex]\frac{5}{12}[/tex]
= [tex]-\frac{3}{5} +\frac{1}{2}[/tex] × [tex]\frac{1}{12}[/tex]
= [tex]-\frac{3}{5} +\frac{1}{24}[/tex]
A= - [tex]\frac{67}{120}[/tex]
B= [tex]\frac{8}{7} (\frac{-9}{7} +\frac{-10}{13} )[/tex]
= [tex]\frac{8}{7} (-\frac{187}{91} )[/tex]
=[tex]-\frac{8}{7} \\[/tex] × [tex]\frac{187}{91}[/tex]
= [tex]-\frac{8*187}{7*91}[/tex]

E = 4/21/7
=2/21 ÷ 7
=4/21 × 1/7
=4×1/21×7
