 how to calculate percent in under one minute. The first part of the calculation is to understand the difference between the two numbers. To do that, I'm going to do an equal sign, open brackets, and value number two minus value number one, close brackets and hit enter. There's a change of five between 15 and 10. What we want to now do is work out what five is as a percentage of value number one. Go back into your calculation, add the divide symbol, select value number one, hit enter. We have the value of 0.5. If I copy this down, convert this to a percentage, we can see that for 10 to turn into 15, it has to increase by 50%. In our second example, we just want to compare the two values. In order to do that, all we need to do is go equal sign, select value number two, divide by value number one, and hit enter. Copy formula down, convert to a percentage. 15 is 150% of 10. Alternatively, value of 10 is 67% of 15. If you enjoyed that video, please don't forget to like, subscribe, and follow for more videos.
