Answer 1

Answer:

27/125, 5.1875

Step-by-step explanation:

$\dfrac{2 \dfrac{1}{2} + \dfrac{1}{5}}{2 \dfrac{1}{2} \div \dfrac{1}{5}}\\\\\\= \dfrac{\dfrac{5}{2} + \dfrac{1}{5}}{\dfrac{5}{2} \times 5}\\\\\\\\= \dfrac{\dfrac{25 + 2}{10}}{\dfrac{25}{2}}\\\\\\\\\\= \dfrac{27}{10} \div \dfrac{25}{2}\\\\\\\\= \dfrac{27 \times 2}{10 \times 25}\\\\\\\\= \dfrac{27}{125}$

_____________________________________________________

$\left( 1 \div \dfrac{2}{9} \right) + \left( 1 \div 3 \dfrac{1}{5} \right) + \left( 1 \div 2 \dfrac{2}{3} \right)\\\\\\\\\\= \dfrac{9}{2} + \dfrac{5}{16} + \dfrac{3}8}\\\\\\\\\\= \dfrac{72 + 5 + 6}{16}\\\\\\\\\\= \dfrac{83}{16}\\\\\\\\= 5.1875$
