Question

直接写出得数． (2)/(3)+(1)/(5)=	5-(5)/(7)=	(7)/(8)+(1)/(8)=	0.5×0.5÷5=	(1)/(3)+(1)/(4)=
(1)/(2)-(1)/(3)=	(4)/(9)+(1)/(3)=	0.4×25-10=	(2)/(5)+(1)/(10)=	(5)/(8)-(2)/(5)=
1+(1)/(2)+(1)/(3)=	(3)/(5)+(3)/(10)=

Answer 1

(2)/(3)+(1)/(5)=(13)/(15)，	5-(5)/(7)=4(2)/(7)，	(7)/(8)+(1)/(8)=1，	0.5×0.5÷5=0.05，	(1)/(3)+(1)/(4)=(7)/(12)，
(1)/(2)-(1)/(3)=(1)/(6)，	(4)/(9)+(1)/(3)=(7)/(9)，	0.4×25-10=0，	(2)/(5)+(1)/(10)=(1)/(2)，	(5)/(8)-(2)/(5)=(9)/(40)，
1+(1)/(2)+(1)/(3)=1(5)/(6)，	(3)/(5)+(3)/(10)=(9)/(10)．
