$H =$ $\dfrac{5}{8}$ $+$ $\dfrac{-3}{4}$ $+$ $\dfrac{7}{12}$ $+$ $\dfrac{1}{24}$
$=$ $\dfrac{5.3}{8.3}$ $+$ $\dfrac{-3.6}{4.6}$ $+$ $\dfrac{7.2}{12.2}$ $+$ $\dfrac{1}{24}$
$=$ $\dfrac{15-18+14+1}{24}$
$=$ $\dfrac{12}{24}$
$=$ $\dfrac{1}{2}$
$= 0,5$
$I=$$\dfrac{1}{2}$ $+$ $\dfrac{-1}{57}$$ +$ $\dfrac{1}{3}$ $+$ $\dfrac{1}{6}$
$=$ $\dfrac{1.57}{2.57}$ $+$ $\dfrac{1.38}{3.38}$ $+$ $\dfrac{-1.2}{57.2}$ $+$ $\dfrac{1.19}{6.19}$
$=$ $\dfrac{57+38-2+19}{114}$
$=$ $\dfrac{112}{114}$
$=$ $\dfrac{56}{57}$
