Question

直接写得数 20%+80%=	(3)/(4)−(1)/(4)=	60%÷(1)/(5)=
(1)/(7)×(2)/(3)=	(21)/(25)÷42%=	10÷10%=
4÷((3)/(4)+(1)/(2)−1)=	(7)/(8)×(11)/(15)×1(1)/(7)×1(4)/(11)=

Answer 1

20%+80%=1，	(3)/(4)−(1)/(4)=(1)/(2)，	60%÷(1)/(5)=3，
(1)/(7)×(2)/(3)=(2)/(21)，	(21)/(25)÷42%=2，	10÷10%=100，
4÷((3)/(4)+(1)/(2)−1)=16，	(7)/(8)×(11)/(15)×1(1)/(7)×1(4)/(11)=1．
