求解步骤

\frac{5}{10} + \frac{8}{100}

消掉

\frac{5}{10} : \frac{1}{2}

= \frac{1}{2} + \frac{8}{100}

消掉

\frac{8}{100} : \frac{2}{25}

= \frac{1}{2} + \frac{2}{25}

\frac{1}{2} + \frac{2}{25} = \frac{29}{50}

= \frac{29}{50}

180/20

j o in \frac{2}{5} k - \frac{3}{5} + \frac{1}{10} k

s im pl i f y 250%

so l v e f or x, \frac{2}{3} x = 5

so l v e f or k, \frac{k}{4} + 3 = 14
