I think it is 20% because I did $$\frac{ 1 }{ 5 }\times 100= 0.02 \times 100 = 20%$$

1/5 individuals means that 20% of the sample owns a bike
margin of error of 1.5% means that the actual value could be between

20-1.5% to 20+1.5%
which means that the minimum value is 18.5% and the maximum value is 21.5%
