Question

直接写出得数

(4)/(5)+2=	1-(2)/(7)=	(7)/(10)-(3)/(10)=	0.8×125-10=	(2)/(5)+(3)/(5)=
(1)/(5)+(3)/(5)-(4)/(5)=	(5)/(7)+(5)/(14)=	(3)/(4)+(1)/(7)=	5×1.4-0.4×5=	(7)/(8)-(2)/(9)=

Answer 1

(4)/(5)+2=2(4)/(5)	1-(2)/(7)=(5)/(7)	(7)/(10)-(3)/(10)=(2)/(5)	0.8×125-10=90	(2)/(5)+(3)/(5)=1
(1)/(5)+(3)/(5)-(4)/(5)=0	(5)/(7)+(5)/(14)=(15)/(14)	(3)/(4)+(1)/(7)=(25)/(28)	5×1.4-0.4×5=5	(7)/(8)-(2)/(9)=(47)/(72)
