（2013•福田区模拟）直接写出得数．

3.7+(1)/(2)=	(2)/(7)-(2)/(7)÷3=	4.8+3(2)/(5)+5.2+6.4=
4(5)/(8)×24=	569-399=	21(3)/(4)-5(2)/(9)-3(2)/(9)=

3.7+(1)/(2)=	(2)/(7)-(2)/(7)÷3=	4.8+3(2)/(5)+5.2+6.4=
4(5)/(8)×24=	569-399=	21(3)/(4)-5(2)/(9)-3(2)/(9)=

3.7+(1)/(2)= (2)/(7)-(2)/(7)÷3= 4.8+3(2)/(5)+5.2+6.4=3.7+(1)/(2)=(1)/(2)=(1)/(2)1122(2)/(7)-(2)/(7)÷3=(2)/(7)-(2)/(7)÷3=(2)/(7)2277(2)/(7)÷3=(2)/(7)22774.8+3(2)/(5)+5.2+6.4=(2)/(5)+5.2+6.4=(2)/(5)2255 4(5)/(8)×24= 569-399= 21(3)/(4)-5(2)/(9)-3(2)/(9)=4(5)/(8)×24=(5)/(8)×24=(5)/(8)5588569-399=21(3)/(4)-5(2)/(9)-3(2)/(9)=(3)/(4)-5(2)/(9)-3(2)/(9)=(3)/(4)3344(2)/(9)-3(2)/(9)=(2)/(9)2299(2)/(9)=(2)/(9)2299

Answer 1

3.7+(1)/(2)=4.2	(2)/(7)-(2)/(7)÷3=(4)/(21)	4.8+3(2)/(5)+5.2+6.4=19.8
4(5)/(8)×24=111	569-399=170	21(3)/(4)-5(2)/(9)-3(2)/(9)=13(11)/(36)．
