Question

Efectúa
(1/2 + 1/3 + 1/4) ÷ ( 2/5 + 4/5 )​

Answer 1

$( \frac{1}{2} + \frac{1}{3} + \frac{1}{4} ) \div ( \frac{2}{5} + \frac{4}{5} )$

$( \frac{1}{2} + \frac{1}{3} + \frac{1}{4} ) = \frac{6 + 4 + 3}{12} = \frac{13}{12}$

$( \frac{2}{5} + \frac{4}{5} ) = \frac{6}{5}$

$\frac{13}{12} \div \frac{6}{5} = \frac{65}{72}$
