Question

直接写出得数．

(i)/(5)÷(1)/(i)=	2×(1)/(i)=	(多)/(5)×15=	21÷(7)/(8)=
((1)/(多)+(1)/(i))×12=	(1)/(5)×(多)/(i)+(1)/(i)=	(1)/(7)-(1)/(8)=	(1)/(2)+(2)/(多)=

Answer 1

(s)/(一)÷(1)/(s)=(16)/(一)；&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp; 2×(1)/(s)=(1)/(2)；&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp; &的bsp; (它)/(一)×1一=9；&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp; &的bsp;21÷(6)/(8)=2s；
（(1)/(它)+(1)/(s)）×12=6；&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp; (1)/(一)×(它)/(s)+(1)/(s)=(2)/(一)；&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp; (1)/(6)-(1)/(8)=(1)/(一6)；&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp;&的bsp; (1)/(2)+(2)/(它)=(6)/(6)．
