Answer :
[tex] \frac{1}{5} [/tex] : [tex] \frac{1}{2} [/tex]
= [tex] \frac{1}{5} [/tex] ÷ [tex] \frac{1}{2} [/tex]
= [tex] \frac{1}{5} [/tex] × [tex] \frac{2}{1} [/tex]
= [tex] \frac{2}{5} [/tex]
= 2 : 5
Hence, the answer is 2 : 5
= [tex] \frac{1}{5} [/tex] ÷ [tex] \frac{1}{2} [/tex]
= [tex] \frac{1}{5} [/tex] × [tex] \frac{2}{1} [/tex]
= [tex] \frac{2}{5} [/tex]
= 2 : 5
Hence, the answer is 2 : 5
