20 is 50% of what number? If necessary, round to the nearest tenth. Is it 10.0?

100 % of a no. is that no. itself if the percent is less than 100 then the resultant no. will be less than our original no. Here 20 is 50% of some no. so that no. has to be greater than 20. Do you get this?

yeah, but let's solve to find that \[50 \% x=20\] \[\frac {50}{100} \times x=20\] Now solve this for x
