(1.4+25分之一)十1.12-六分之一
=1.4+1/25+1.12-1/6
=1.4+1.12+1/25-1/6
=2.52+6/150-25/150
=2.52-19/150
=2又52/100-19/250
=(2+52/100)-19/250
=2+13/25-19/250
=2+130/250-19/250
=2+121/250
=2又121/250

回答2:

解:原式=(1.4+0.04)+1.12-(1/6)
=1.44+1.12-(1/6)
=2.56-(1/6)
=2+0.56-(1/6)
=2+(56/100)-(1/6)
=2+(168/300)-(50/300)
=2+(168-50)/300
=2+118/300
=2又59/150
