2.25×1.8-12.5×0.18= 3/8+5/8÷5/6=
简便计算.是2道题的.

2.25×1.8-12.5×0.18
=22.5×0.18-12.5×0.18
=0.18×(22.5-12.5)
=1.8
3/8+5/8÷5/6
=3/8+5/8×6/5
=3/8+ 6/8
=1又1/8

2.25×1.8-12.5×0.18= 3/8+5/8÷5/6= 15.8-（6又5分之2+8分之1÷12.5%）= 4/15×6/8= 3/8÷12= 4/5×5/6= 36×5/18= （9.3×5/6－7又3/10）÷2.25 （8又1/4－6又4/15）÷（2又1/3+4.2）×7 1.8-[1÷（2 简便运算：【5-3又7/8÷(1又5/6+2.25×1/3)】÷0.125 (5y+1)÷6=(9y+1)÷8-(1-y)÷3 [5-3又8分之7/（1-6分之5+2.25*3分之1）]/0.125=? 8分之3÷X=5分之3 6分之5—5X=12分之5 3/5x=8/15÷5/12.（x+1/2）÷5/24=8/9÷1/6 那1+2÷3x4+5+6-7÷8=1 1 2 3 4 5 6 7 8=1（空里添+-*/()）*=×/=÷ 1÷2÷3÷4÷5÷6÷7÷8÷9=2.8添上括号使等式成立
