I=\(\dfrac{5.6}{4.6}+\dfrac{-1.8}{3.8}+\dfrac{5}{24}=\dfrac{30-8+5}{24}=\dfrac{27}{24}\)
J=\(\dfrac{-19.-10}{-9.-10}+\dfrac{4.-9}{-11.-9}-\dfrac{-2.33}{3.33}=\dfrac{190-36+66}{99}=\dfrac{40}{99}\)
K=\(\dfrac{-5.2}{6.2}-\dfrac{7}{12}+\dfrac{-3}{4.3}=\dfrac{-10-7-3}{12}=\dfrac{-20}{12}\)
L=\(\dfrac{-3.3}{20.3}+\dfrac{1.12}{5.12}-\dfrac{-5.20}{3.20}=\dfrac{-9+12+100}{60}=\dfrac{103}{60}\)
