How to Find the Increased Percentage of a ValueBy Marija Kero
Finding the increased percentage of a value will require you to look closely at both old and new values. Find the increased percentage of a value with help from an experienced mathematics professional in this free video clip.
Hi, my name is Marija, and today I'm going to show you how to find the increased percentage of a value. So to find the percent of increase what we're going to do is we're going to take the new value minus the old value before it was increased and we're going to divide it by the old value. And then we're going to take this proportion and we're going to multiply it by 100 in order to make it a percent. So if the number has increased from ten to 15, we're going to take the new value 15, we'll subtract the old value or the original value, which was ten, and then we'll divide that by the old value or original value which is ten. So now once we simplify this fraction we get 15 minus ten is five over ten we get five over ten which is the same thing as one half or .5 and we multiply that by 100. We multiply by 100 and we get 50 percent. So that means that when this value increased from ten to 15 the percentage of increase was 50 percent. So again we just took the new value, subtracted the old value from it, then we divided by the old value and once we simplified this fraction in to a decimal we multiplied by 100 and we got our percent of increase.
