①9又6分之5-2.19-(1.81-1/6) ②(8又6分之5-10.5×4/5)÷4又3分之一 ③3.14×0.65+4又2分之一×3.14-3又50分之7 ④18.2×25%+4/5×1/4+1/4 ⑤2014×12/47+2014÷

③如果是减算,题目是不是这样的
31.4×0.65+4又2分之1×3.14-3又50分之7
如果是的,则
原式=3.14×(6.5+4.5-1)
=3.14×10
=31.4
④
=1/4×(18.2+4/5+1)
=1/4×20
=5⑤ =2014×(12/47+35/47) =2014×1 =2014⑥ =0.125×2.75+0.125×4.25+0.125 =0.125×(2.75+4.25+1) =0.125×8 =1⑦ =2047÷(5.75-4.5×20％-4.5×1/3) =2.35÷(5.75-0.9-1.5) =2.35÷3.35 (题目是不是有问题) =47/67⑦ =20分之47÷(5.75-4.5×20％-4.5×1/3) =2.35÷(5.75-0.9-1.5) =2.35÷3.35 (题目是不是有问题) =47/67⑧ =10/27×(7/8-17/20+1/8) =10/27×(1-17/20) =10/27×3/20 =1/18
