Calculating the percent of a number is simple, but can be a bit tricky if you aren't careful. Luckily, it only requires a few basic operations to get to the solution: multiplication and division. If you haven't learned what percentage is yet, or would like a little refresher, feel free to check out our introduction to percentage page. To solve percentage problems, it may be useful to use a calculator. But, they can also be solved by hand or in your head (if you practice enough). So, how did we get to the solution that 97 percent of 157 = 152.29? **Step 1:**As we know, a whole of something is equal to 100%. In this case, we want to find what 97% of 157 is. We know that 100% of 157 is, well, just 157.**Step 2:**If 100% of 157 is 157, then we can get 1% of 157 by dividing it by 100. Let's do 157 / 100. This is equal to 1.57. Now we know that 1% is 1.57.**Step 3:**Now that we know what 1% of 157 is, we just need to multiply it by 97 to get our solution! 1.57 times 97 = 152.29. That's all there is to it!
