Question

直接写出结果． (2)/(3)-(1)/(2)=	4.5×102=	341-103=	270÷18=
10×10%=	5-0.25+0.75=	0.42-0.32=	2÷(1)/(5)=
(5)/(9)×6=	4.57+6.43=	7×(1)/(7)÷7×(1)/(7)=	1÷(4)/(5)×(3)/(5)=

Answer 1

(2)/(3)-(1)/(2)=(1)/(6)        4.5×102=459        341-103=238              270÷18=15 
10×10%=1         5-0.25+0.75=5.5      0.4²-0.3²=0.07             2÷(1)/(5)=10
(5)/(9)×6=3(1)/(3)           4.57+6.43=11        7×(1)/(7)÷7×(1)/(7)=(1)/(49)           1÷(4)/(5)×(3)/(5)=(3)/(4)
