六年级分数试卷

1. 7/8除以56.34-87.5除以5634（要过程）
2. 12.8除以｛[3有1/5X（5-2.8除以14/15）]+（26/5-13X0.4）｝
过程

Answer 1

1. 7/8除以56.34-87.5除以5634
=7/8/(56.34)-87.5/5634
=7/8*100/5634-87.5/5634
=1/5634*(700/8-87.5)
=1/5634*0
=0
2. 12.8除以｛[3有1/5X（5-2.8除以14/15）]+（26/5-13X0.4）｝
=12.8/{[16/5*(5-2.8/14/15)]+(26/5-5.2)}
=12.8/{[16-(16*2.8)/(5*210)+0}
=12.8/{16-6.4/150}
=12.8/2393.6/150
=12.8/359040
=1/28050 .

Answer 2

1. 7/8除以56.34-87.5除以5634
=7/8/(56.34)-87.5/5634
=7/8*100/5634-87.5/5634
=1/5634*(700/8-87.5)
=1/5634*0
=0
2. 12.8除以｛[3有1/5X（5-2.8除以14/15）]+（26/5-13X0.4）｝
=12.8/{[16/5*(5-2.8/14/15)]+(26/5-5.2)}
=12.8/{[16-(16*2.8)/(5*210)+0}
=12.8/{16-6.4/150}
=12.8/2393.6/150
=12.8/359040
=1/28050 .
