分数乘法分数乘整数  分数乘整数,用分数的分子和整数相乘的积做分子,分母不变。能约分(化简)的要约分(化简)。 例1:4/5×3=4×3/5=12/5
例2:3/22×2=2×3/22=6/22=3/11分数乘分数  分数乘分数,用分子相乘的积做分子,分母相乘的积做分母。能约分(化简)的要约分(化简)。 例1:5/6×1/3=5×1/6×3=5/18
例2:2/5×1/4=2×1/5×4=2/20=1/10
编辑本段分数除法分数除以整数(1)  分数除以整数,分母不变,如果分子是整数的倍数,则用分子除以整数,最后不是最简分数要化成最简分数。
例1:4/15÷2=4÷2/15=2/15
例2:42/30÷7=42÷7/30=6/30=1/5分数除以整数(2)  分数除以整数,分母不变,如果分子不是整数的倍数,则用这个分数乘这个整数的倒数,最后不是最简分数要化成最简分数。
例1:3/8÷2=3/8×1/2=3×1/8×2=3/16
例2:4/5÷6=4/5×1/6=4×1/5×6=4/30=2/15分数除以分数  分数除以分数,等于被除数乘除数的倒数,最后不是最简分数要化成最简分数。
例1:2/3÷3/4=2/3×4/3=2×4/3×3=8/9
例2:2/15÷1/3=2/15×3=2×3/15=6/15=2/5
整数除以分数
分数除法换算成分数乘法。一个分数除另一个分数等于乘以这个分数的倒数,整数可以化成分母为1的假分数。
例:21÷1/3=63/3÷1/3=7

你好,这样的题你最好去百度上搜一下就有的,要是往上打的话是很麻烦的,可能很少有人会把这样的40道题打上去,

1. 7/5*2/3+5/1*7/9
2. 1/8*2/3+5/8*4/5
3. 10*5/9-2/5*125
