\(\frac{2}{5}\)= \(\frac{14}{35}\) ; \(\frac{4}{7}\)=\(\frac{20}{35}\)
\(\frac{14}{35}\)< \(\frac{a}{35}\)<\(\frac{b}{35}\)<\(\frac{c}{35}\)<\(\frac{d}{35}\)<\(\frac{e}{35}\)< \(\frac{20}{35}\)
\(\Rightarrow\)a=15, b=16,c=17,d=18,d=19
5 p/s cần tìm là : \(\frac{15}{35}\),\(\frac{16}{35}\),\(\frac{17}{35}\),\(\frac{18}{35}\)và \(\frac{19}{35}\)
5 phân số đó là :
\(\frac{3}{5},\frac{16}{35},\frac{17}{35},\frac{18}{35},\frac{19}{35}\)
