Question

How does the definition of PERCENT help you write fraction and decimals equivalents?

Answer 1

The definition of percent is out of one hundred. per = out of, cent = hundred
You can turn any fraction into a decimal by dividing the numerator by the denominator (the top by the bottom), and you can turn any decimal into a percentage by moving the decimal point to the right two places.
Example: 3/4 turns into 0.750, and 0.750 turns into 75.0%
In doing this, it's easier to find whether or not two fractions or decimals are equivalent, because they're in the same form, and you don't have to go through the hassle of finding a common denominator.

Answer 2

By definition we have to:
 The percentage is a mathematical symbol, which represents a given quantity as a fraction in 100 equal parts. It is also commonly called percent where percent means "out of every hundred units."
 We have then that using the definition we can apply the following formula to obtain a fraction or a decimal:
 $\frac{A}{100}$
 Where,
 A: amount in percentage
 Answer:
 you can write fraction and decimals equivalents using the expression:
 $\frac{A}{100}$
