以下是分数乘法100道算式的整理,分基础题、进阶题和综合题三类:
一、基础题(分数乘整数)
-
$\frac{2}{1} \times 8 = 16$
-
$\frac{5}{8} \times 4 = \frac{5}{2}$
-
$\frac{6}{5} \times 5 = 6$
-
$\frac{8}{7} \times 7 = 8$
-
$\frac{6}{5} \times 10 = 12$
-
$3 \times \frac{7}{4} = \frac{21}{4}$
-
$5 \times \frac{8}{9} = \frac{40}{9}$
-
$10 \times \frac{3}{11} = \frac{30}{11}$
-
$12 \times \frac{5}{6} = 10$
-
$14 \times \frac{2}{7} = 4$
二、进阶题(分数乘分数)
-
$\frac{1}{2} \times \frac{6}{5} = \frac{3}{5}$
-
$\frac{1}{7} \times \frac{7}{5} = \frac{1}{5}$
-
$\frac{1}{7} \times \frac{1}{8} = \frac{1}{56}$
-
$\frac{8}{9} \times \frac{2}{7} = \frac{16}{63}$
-
$\frac{1}{22} \times \frac{22}{4} = \frac{1}{4}$
-
$\frac{3}{8} \times \frac{4}{9} = \frac{1}{6}$
-
$\frac{5}{12} \times \frac{3}{5} = \frac{1}{4}$
-
$\frac{7}{16} \times \frac{2}{7} = \frac{1}{8}$
-
$\frac{2}{3} \times \frac{9}{10} = \frac{3}{5}$
-
$\frac{4}{5} \times \frac{5}{8} = \frac{1}{2}$
三、综合题(混合运算)
-
$\frac{3}{4} \times \frac{2}{3} + \frac{1}{2}$
-
$\frac{5}{6} \times \frac{3}{5} - \frac{1}{3}$
-
$\frac{2}{7} \times \frac{7}{8} + \frac{1}{4}$
-
$\frac{3}{10} \times \frac{5}{6} - \frac{1}{10}$
-
$\frac{4}{9} \times \frac{9}{10} + \frac{1}{5}$
说明 :以上题目均基于分数乘法的基本规则,包括分数乘整数、分数乘分数及混合运算。建议根据学习进度选择难度,基础题巩固运算规则,进阶题提升计算能力,综合题加强实际应用。
