Question

直接写得数．

(1)/(5)+(1)/(2)=	1-(13)/(18)=	3+(5)/(18)=	(1)/(9)-(1)/(10)=
(8)/(9)×45=	(6)/(5)×5=	(11)/(12)×(3)/(8)=	(3)/(4)×(1)/(6)=

Answer 1

(1)/(5)+(1)/(2)=(7)/(10)	1-(13)/(18)=(5)/(18)	3+(5)/(18)=3(5)/(18)	(1)/(9)-(1)/(10)=(1)/(90)
(8)/(9)×45=40	(6)/(5)×5=6	(11)/(12)×(3)/(8)=(11)/(32)	(3)/(4)×(1)/(6)=(1)/(8)
