who来帮我出计算题!老师要我们做100道分数小数的混合运算,请帮我出题!发题目的时候发的清楚点,让我看得清.请尽量多的出题,如果是在出不了那么多可以出五十题也没问题!还有2/1*2=1这样的太简单了,要再复杂点,但是巧算起来简单的.

2/1*2=1 3/1*3=1 3/2*3=2 3/1*6=2
4/3*8=6 5/3*20=12 7/3*14=6 8/7*40=35
4/3*16=12 9/5*27=15 2/1*30=15 12/7*24=14
30/1*30=1 51/9*102=18 19/9*76=36 4/9*8=18
5/8*90=144 99/98*99=98 3/14*6=28 7/1*28=4
10/1*90=9 5/3*105=63 19/7*38=14 5/1*25=5
8/19*16=38 61/60*122=120 7/2*28=8 6/1*48=8
9/7*18=14 25/7*100=28 9/5*81=45 8/9*16=18
