1.5×7/13+6/13×3/2
=1.5×(7/13+6/13)
=1.5×1
=1.5
0.125×3/10+1/8×0.7
=0.125×(3/10+0.7)
=0.125×1
=0.125
0.25×1.7-1/10×1/4
=0.25×(1.7-1/10)
=0.25×1.6
=0.4
=1.5×(7/13+6/13)
=1.5×1
=1.5
0.125×3/10+1/8×0.7
=0.125×(3/10+0.7)
=0.125×1
=0.125
0.25×1.7-1/10×1/4
=0.25×(1.7-1/10)
=0.25×1.6
=0.4

71×25/44+25×17/44
=71×25/44+17×25/44
=(71+17)×25/44
=88×25/44
=50
注:7应该是17才以实现简便计算。
25×7/13-7×12/13
=25×7/13-12×7/13
=(25-12)×7/13
=13×7/13
=7
