17/25X5/37+8/25X17/37+17/37X2/25 用简便方法怎么做
17/25X5/37+8/25X17/37+17/37X2/25
=17/(25×37)×(5+8+2)
=17×15/(25×37)
=17/37×15/25
=17/37×3/5
=51/185
计算17/25x5/9 8/25x17/9 17/9x2/25
17/25x5/9
=17/(5*9)
=17/45
8/25x17/9
=136/225
17/9x2/25
=34/225
17/25x5/33+8/25x17/33+17/33x2/25=
17/25x5/33+8/25x17/33+17/33x2/25
=17/25x5/33+17/25x8/33+17/25x2/33
=17/25x（5/33+8/33+2/33）
=17/25x5/11
=17/55

17/25*5/57+8/25*17/37+17/57*2/25
17/25*5/57+8/25*17/57+17/57*2/25
=17/25*5/57+17/25*8/57+17/25*2/57
=17/25x(5/57+8/57+2/57)
=17/25x5/19
=17/95
l7/25x5/19十14/25x17/19的简算
原式=17x(1/25)x5x(1/19)+14x(1/25)x17x(1/19)
=17x(1/25)x[(5x(1/19)+14x(1/19)]
=17x(1/25)x1
=17/25
71x25/44 25x17/44怎样算简便方法
