25/12×16/15×9/4=3600/720=(3600÷5)/(720÷5)=720/144=5
8/45×3/4×5/2=120/24=(120÷3)/(24÷3)=40/8=5
1/2×24/15×25/7=600/210=(600÷5)/(210/5)=120/42=(120÷6)/(42÷6)=20/7
49×5/14×4/25=980/350=(980÷5)/(350÷5)=196/70=(196÷2)/(70÷2)=98/35=(98÷7)/(35÷7)=14/5
2/3-1/4×2/3+5/6=2/3-2/12+5/6=8/12-2/12+10/12=20/12=(20÷4)/(12÷4)=5/3
(5/2+1/4)×(7/11-1/33)=(10/4+1/4)×(21/33-1/33)=11/4×20/33=220/132=(220÷2)/(132÷2)=110/66=(110÷11)/(66÷11)=10/6=(10÷2)/(6÷2)=5/3
