Question

47/35×21/8等于几分之几

Answer 1

等于3又40分之21
47/35×21/8=47/5×3/8=141/40=3又21/40
计算这道题先约分，47/5和21/8约分后就是47/5和3/8(分子和分母约)，47/5×3/8=141/40(分子乘以分子，分母乘以分母)，最后化为带分数就是3又21/40

Answer 2

47/35×21/8等于141/40
47/35×21/8
=47/5×3/8
=47×3/5×8
=141/40
乘除法二则运算,从左到右依次计算,分数相乘,分子与分子相乘,分母与分母相乘,能约分的先约分,答案为最简分数47/35x21/8

Answer 3

47/35×21/8等于141/40
47/35×21/8
=47/5×3/8
=47×3/5×8
=141/40
乘除法二则运算,从左到右依次计算,分数相乘,分子与分子相乘,分母与分母相乘,能约分的先约分,答案为最简分数47/35x21/8

Answer 4

47/35×21/8等于40分之141
解:47/35×21/8=47/5×3/8=141/40

Answer 5
