13.直接写出得数.
0.1-0.01= | $\frac{7}{9}$÷7= | 1÷$\frac{1}{4}$÷1= | 5-$\frac{5}{8}$= |
$\frac{7}{20}$×$\frac{20}{7}$= | 1÷$\frac{1}{3}$-$\frac{1}{3}$÷1= | 0.24×5= | $\frac{3}{4}$×$\frac{8}{9}$= |
$\frac{5}{14}$×$\frac{2}{15}$= | 5.8×9+5.8= | 7-$\frac{1}{6}$-$\frac{5}{6}$= | $\frac{4}{5}$÷$\frac{3}{5}$÷$\frac{4}{5}$×$\frac{3}{5}$= |
12.甲、乙两根电线同样长.如果甲剪掉$\frac{1}{5}$,乙剪掉$\frac{1}{5}$米后,这两根电线相比较是( )
