3. 解方程。(6 分)
$\frac{2}{3}x = \frac{4}{5}$ $\frac{8}{5}x = \frac{4}{7}$ $\frac{7}{13}x = 1$
$\frac{2}{3}x = \frac{4}{5}$ $\frac{8}{5}x = \frac{4}{7}$ $\frac{7}{13}x = 1$
答案:
解方程
1. $\frac{2}{3}x = \frac{4}{5}$
解:$x = \frac{4}{5} ÷ \frac{2}{3} = \frac{4}{5} × \frac{3}{2} = \frac{12}{10} = \frac{6}{5}$
2. $\frac{8}{5}x = \frac{4}{7}$
解:$x = \frac{4}{7} ÷ \frac{8}{5} = \frac{4}{7} × \frac{5}{8} = \frac{20}{56} = \frac{5}{14}$
3. $\frac{7}{13}x = 1$
解:$x = 1 ÷ \frac{7}{13} = 1 × \frac{13}{7} = \frac{13}{7}$
1. $\frac{2}{3}x = \frac{4}{5}$
解:$x = \frac{4}{5} ÷ \frac{2}{3} = \frac{4}{5} × \frac{3}{2} = \frac{12}{10} = \frac{6}{5}$
2. $\frac{8}{5}x = \frac{4}{7}$
解:$x = \frac{4}{7} ÷ \frac{8}{5} = \frac{4}{7} × \frac{5}{8} = \frac{20}{56} = \frac{5}{14}$
3. $\frac{7}{13}x = 1$
解:$x = 1 ÷ \frac{7}{13} = 1 × \frac{13}{7} = \frac{13}{7}$
