    $\dfrac{1}{23}$ $+$ $\dfrac{2}{57}$ $+$ $1$ $+$ $\dfrac{8}{19}$ $+$ $\dfrac{9}{20}$
    $=$ $\dfrac{103}{1311}$ $+$ $1$ $+$ $\dfrac{8}{19}$ $+$ $\dfrac{9}{20}$
    $=$ $\dfrac{1414}{1311}$ $+$ $\dfrac{8}{19}$ $+$ $\dfrac{9}{20}$
    $=$ $\dfrac{1966}{1311}$ $+$ $\dfrac{9}{20}$
    $=$ $1,9496….$
