What is $ 2.5 $ percent as a decimal?

Hint: Percentage can be defined as the fraction where the denominator is always hundred. Here we will take the given data, frame it in the form of percentage and then convert the percentage in the form of decimal by placing a decimal point.

Complete step-by-step answer:
Given that: to convert the $ 2.5 $ percent as a decimal
Convert the given word statement in the form of the mathematical expression.
 $ = 2.5\% $
Percentage can be defined as the numerator upon the denominator as the hundred.
 $ = \dfrac{{2.5}}{{100}} $
To convert the given number in the decimal form. Move the decimal point towards the left hand side of the number from the right hand side of the term and since we have two zeroes in the denominator move two digits.
 $ = 0.025 $
Hence, $ 2.5 $ percent as a decimal is $ 0.025 $

Note: Do not get confused between the two terms fraction and the percentage. Fractions are defined as the part of the whole and is expressed as the numerator upon the denominator. While simplifying the fraction, it always tries to convert the denominator in tens, hundreds and directly shift the decimal point which is dependent on the number of zeros in the denominator.
