怎么简便就这样算

14.75-（5又4分之3-1又12分之1）
=14.75-[(5+3/4)-(1+1/12)]
=14.75-5.75+1+1/12
=9+1+1/12
=10+1/12
=10又12分之1

5.48-0.75+4又二十五分之十三-2又4分之1
=5.48-0.75+(4+13/25)-(2+1/4)
=5.48-0.75+4.52-2.25
=(5.48+4.52)-(0.75+2.25)
=10-3
=7

19又6分之5-（5.875-1又12分之11）+2又24分之5
=(19+5/6)-[(5+7/8)-(1+11/12)]+(2+5/24)
=19+5/6-5-7/8+1+11/12+2+5/24
=(19-5+1+2)+(-21/24+20/24+22/24+5/24)
=22+26/24
=23+1/12
=23又12分之1

计算器

14.75-（5又4分之3-1又12分之1）
=59/4-(23/4-13/12)
=59/4-[(69-13)/12]
=59/4-14/3
=(177-56)/12
=121/12

5.48-0.75+4又二十五分之十三-2又4分之1
=548/100-3/4+113/25-9/4
=548/100+113/25-9/4-3/4
=(548+452)/100-3
=10-3
=7

19又6分之5-（5.875-1又12分之11）+2又24分之5
=119/6-[(5875/1000)-(23/12)]+53/24
=119/6-[(47/8)-(23/12)]+53/24
=119/6-[(141-46)/24]+53/24
=119/6-95/24+53/24
=(476-95+53)/24
=434/24
=217/12
