62分之61乘63 简便计算
62分之61乘63
=61/62*(62+1)
=61/62*62+61/62
=61+61/62
=61又61/62

=62分之61×(62+1)
=62分之61×62+62分之61×1
=61+62分之61
=61又62分之61

解62分之61乘63
=61/62*63
=61/62*(62+1)
=61+61/62
=61又61/62

61/62x63
=61/62x(62+1)
=61/62x62+61/62x1
=61+61/62
=61又61/62

62/61×63
=62/61×(62+1)
=62/61×62+62/61×1(乘法分配律)
=61+62/61
=61又62/61

(61/62)*63
(61/62)*(62+1)
=(61/62)*62+(62/61)*1
=61+(61/62)
=62又61/62
