Question

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

Answer 1

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?

Answer 2

oh okay :) so then it would be like 40?

Answer 3

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

Answer 4

50/100=0.5...so then..20/0.5 equals...40!!! :O :D wait did i do that right?
