33/160 = 20.6% or 21%
In order to accomplish this,
1. Divide 33 by 160 (answer should be decimal; answer is 0.20625)
2. Multiply the answer by 100 (the answer would now be 20.625)
3. In most cases, decimal could be included in problems so I will round it of to the tenths place. (THIS STEP IS OPTIONAL)
4. Put a percentage sign next to the value.
