Corona again

If the population on long island is 7.75 million and the coronavirus has affected 22,178. What percent of the population is affected. (looking for 1 in? If possible)

Result

p =  0.286 %
r =  1:349

Solution:

p=100⋅ 221787.75⋅ 1e6≐0.2862=0.286%p=100 \cdot \ \dfrac{ 22178 }{ 7.75 \cdot \ 1e_{6} } \doteq 0.2862=0.286 \%
r=1[7750000/22178]=1349≐0.0029≈0.0029≐1:349r=\dfrac{ 1 }{ [ { 7750000/22178 } ] }=\dfrac{ 1 }{ 349 } \doteq 0.0029≈ 0.0029 \doteq 1:349
