Ratios and fractions

jeudi 31 juillet 2014

Why can ratios be written as fractions?



if there are 5 men in 20 people the ratio of men to total people is 5:20 which is 1:4.



But when we write 1/4 it gives 0.25. And 0.25 means the magnitude of each part when 1 is divided into 4 equal parts.



So how does ratio and fraction give a same meaning? Please explain it to me.
