write 9:50 as a percent
It depends
If you want the first as a percenage of the second than it is certainly 18%
BUT
If you want the first as a percentage of the whole it is 9/59*100% = approx 15.25%
18%
9/50 is the same as 18/100. When you divide 9 by 50 (or 18 by 100) you get .18, or 18%.
If that is a ratio, then we have:
9/50 X 100=18%
+1243
