化简 1/5+1/3-5/6+4/10

解答

化简

\frac{1}{5} + \frac{1}{3} - \frac{5}{6} + \frac{4}{10}

\frac{1}{10}

十进制

0.1

求解步骤

\frac{1}{5} + \frac{1}{3} - \frac{5}{6} + \frac{4}{10}

消掉

\frac{4}{10} : \frac{2}{5}

= \frac{1}{5} + \frac{1}{3} - \frac{5}{6} + \frac{2}{5}

\frac{1}{5} + \frac{2}{5} = \frac{3}{5}

= \frac{3}{5} + \frac{1}{3} - \frac{5}{6}

\frac{3}{5} + \frac{1}{3} - \frac{5}{6} = \frac{3}{30}

= \frac{3}{30}

对数字约分

\frac{3}{30} = \frac{1}{10}

= \frac{1}{10}

3 x + 2 = 5 x - 3

f a c t or 96 x^{3} + 120 x^{2} + 24 x + 30

f a c t or 3 u^{4} - 3 u^{4} y^{4}

y^{2} + 6 y - 40 = 0

10 x^{2} - 17 x + 3 = 0
