问题描述:

(1)1375-375÷15×18= (2)40.5÷0.81-16×0.24= (3)2/5×25×5/6×4= (4)12×(1/4+1/6+1/3)=
(5)(3/10×5/6+3/10)÷9/4= 能简便运算就简便运算
列式计算
(1)2.63与2.37的和除以0.25,所得的商比25少多少?
(2)1/5与6的倒数之和,除以5/6与3/8的差,商是多少?

一、能简便运算就简便运算.(1)1375-375÷15×18 =100×18÷15 =120(2)40.5÷0.81-16×0.24 =50-3.84 =46.16(3)2/5×25×5/6×4 =(2/5×25)×(5/6×4) =10×10/3 ...
