(1) (5/9*4.5-2/1.25)/7
(2) (4-35/65*5.2)/0.01
(3) 18.25*59/5-(17+1/4)/(1-54/59)
(4) 0.1/(3.3-(2.4+18/5/6))
(5) 0.5*236*59/119

(1) (5/9*4.5-2/1.25)/7(2) (4-35/65*5.2)/0.01(3) 18.25*59/5-(17+1/4)/(1-54/59)(4) 0.1/(3.3-(2.4+18/5/6))(5) 0.5*236*59/119
(1) ((5/9)×(9/2)-2/(5/4))/7=(5/2-5/2)/7=0 (2) (4-(35/65)×(26/5))÷(1/100)=(4-14/5)×100=120\7
(3) 18.25×(59/5)-17.25×(59/5)=(18.25-17.25)×(59/5)=59/5\7
(4) 0.1/(3.3-(2.4+18/5/6))
=1/10/(0.9-0.6)=1/3
(5) 0.5*236*59/119=½×236×59/119=118×59/119\7
不知道这样行不行啊
