Answer 2

$\mathrm{Question :\;\dfrac{1}{4\dfrac{2}{7}} + \dfrac{1}{1\dfrac{11}{13}} + \dfrac{1}{\dfrac{5}{9}}}$

$\mathrm{\implies \dfrac{1}{4 + \dfrac{2}{7}} + \dfrac{1}{1 + \dfrac{11}{13}} + \dfrac{9}{5}}$

$\mathrm{\implies \dfrac{1}{\dfrac{7(4) + 2}{7}} + \dfrac{1}{\dfrac{13 + 11}{13}} + \dfrac{9}{5}}$

$\mathrm{\implies \dfrac{1}{\dfrac{28 + 2}{7}} + \dfrac{1}{\dfrac{24}{13}} + \dfrac{9}{5}}$

$\mathrm{\implies \dfrac{1}{\dfrac{30}{7}} + \dfrac{13}{24} + \dfrac{9}{5}}$

$\mathrm{\implies \dfrac{7}{30} + \dfrac{13}{24} + \dfrac{9}{5}}$

$\mathrm{\implies \dfrac{7}{30} + \dfrac{13}{24} + \dfrac{9 \times 6}{5 \times 6}}$

$\mathrm{\implies \dfrac{7}{30} + \dfrac{13}{24} + \dfrac{54}{30}}$

$\mathrm{\implies \dfrac{13}{24} + \dfrac{54 + 7}{30}}$

$\mathrm{\implies \dfrac{13}{24} + \dfrac{61}{30}}$

●  Least Common Multiple of 24 and 30 is 120

$\mathrm{\implies \dfrac{13(5) + 61(4)}{120}}$

$\mathrm{\implies \dfrac{65 + 244}{120}}$

$\mathrm{\implies \dfrac{309}{120}}$

$\mathrm{\implies \dfrac{103}{40}}$
