\frac{1690 ( 36 + 5 3 )}{407}

\frac{60840}{407} + \frac{8450 3}{407}

十进制

185.44429 \dots

求解步骤

\frac{1690 ( 36 + 5 3 )}{407}

乘开

1690 (36 + 53) : 60840 + 84503

= \frac{60840 + 8450 3}{407}

使用分式法则:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{60840 + 8450 3}{407} = \frac{60840}{407} + \frac{8450 3}{407}

= \frac{60840}{407} + \frac{8450 3}{407}
