Question

Answer 1

a) \(\dfrac{5}{8}-\dfrac{3}{4}+\dfrac{15}{6}=\dfrac{15}{24}-\dfrac{18}{24}+\dfrac{60}{24}=\dfrac{57}{24}=\dfrac{19}{8}\)

b) \(\dfrac{17}{2}+\dfrac{3}{7}-\dfrac{5}{3}=\dfrac{357}{42}+\dfrac{18}{42}-\dfrac{70}{42}=\dfrac{305}{42}\)

Answer 2

c) \(\dfrac{1}{2}-\dfrac{3}{4}+\dfrac{5}{6}-\dfrac{7}{12}=\dfrac{6}{12}-\dfrac{9}{12}+\dfrac{10}{12}-\dfrac{7}{12}=0\)

d) \(-3-\dfrac{2}{3}-\dfrac{10}{9}-\dfrac{25}{3}-\dfrac{5}{6}=\dfrac{-54}{18}-\dfrac{12}{18}-\dfrac{20}{18}-\dfrac{150}{18}-\dfrac{15}{18}=\dfrac{-251}{18}\)
