Percent Change Percents are commonly used to measure or report the change in an amount. For example, a news reporter might say, "stocks rose 1. This formula can also be expressed in decimal form.

For example, in order to get a decimal fraction, 3/4 is expanded to 75/ by multiplying the numerator by 25 and denominator by A percentage is a portion of a whole number, where percent is the whole amount.
In other words, percentage means "out of one hundred."

Not sure how to transcribe % in which both the decimal and percent sign are redundant, as only one is necessary if of course they mean 1/4 percent or 25% if unless they do mean "one-fourth of one percent" which would be rather uncommon.
