split the number into its whole number component and decimal component.
for the decimal component, 0.2 is the same as 2/10
Find the GCF of both 2 and 10 and that would be 2
divide both the numerator and denominator by the GCF
simplify and you get 1/5
Lastly combine the whole number component with the fraction and your answer would be 1 1/5.
