33乘以1.03 简便计算 (1.25加1.25加1.25)乘以5加8.75乘以15简便计算
33乘以1.03 简便计算 (1.25加1.25加1.25)乘以5加8.75乘以15简便计算

33乘以1.03 简便计算 (1.25加1.25加1.25)乘以5加8.75乘以15简便计算
33乘以1.03
=33*(1+0.03)
=33*1+33*0.03
=33+0.99
=33.99

(1.25+1.25+1.25)*5+8.75*15
=3.75*5+8.75*(10+5)
=18.75+8.75*10+8.75*5
=18.75+87.5+ 43.75
=18.75+43.75+87.5
=62.5+87.5
=150

33*1+33*0.03 5*(3*1.25+3*9*1.25)=5*(3+27)*1.25=5*30*1.25
