Question

Answer 1

a) = \(\dfrac{17}{3}\) + \(\dfrac{4}{3}\) = \(\dfrac{21}{3}\) 

b) = \(\dfrac{27}{2}\) - \(\dfrac{9}{4}\) = \(\dfrac{57}{4}\) - \(\dfrac{9}{4}\) = \(\dfrac{48}{4}\)

Answer 2

c) = \(\dfrac{25}{7}\) x \(\dfrac{9}{5}\) = \(\dfrac{225}{35}\) 

d) = \(\dfrac{91}{8}\) : \(\dfrac{53}{8}\) = \(\dfrac{8}{91}\) x  \(\dfrac{53}{8}\) = \(\dfrac{424}{728}\)

7 

a) y + \(\dfrac{2}{3}\) = \(\dfrac{5}{2}\) 

y = \(\dfrac{5}{2}\) - \(\dfrac{2}{3}\) 

y = \(\dfrac{11}{6}\) 

b) = \(\dfrac{19}{5}\) - y = \(\dfrac{18}{5}\) 

y = \(\dfrac{19}{5}\) - \(\dfrac{18}{5}\) 

y = \(\dfrac{1}{5}\)
