LCM of 9 and 4 is 2 x 2 x 3 x 3 = 36
5×49×4+−3×94×9=2036+−2736=20+(−27)36=−736\dfrac{5 \times 4}{9 \times 4} + \dfrac{-3 \times 9}{4 \times 9} \\[1em] =\dfrac{20}{36} + \dfrac{-27}{36} \\[1em] =\dfrac{20 + (-27)}{36} \\[1em] =\dfrac{-7}{36}9×45×4+4×9−3×9=3620+36−27=3620+(−27)=36−7
∴ 59+3−4\dfrac{5}{9} + \dfrac{3}{-4}95+−43 = −736\dfrac{-7}{36}36−7
