Question

How do you write $ 0.15 $ in percent form?

Answer 1

Hint:Percentage is the number or ratio expressed as a fraction of hundred. Fractions are the part of the whole. Generally it represents any number of equal parts and it describes the part from a certain size and it is the number expressed in the form of numerator upon the denominator. Know the difference between the fraction and the percentage and apply accordingly.

Complete step by step solution:
Since the percentage is expressed in the denominator as the hundred.
Take the given number $ 0.15 $
Convert the given number in the form of fraction removing the decimal point from it following the number of digits after the point.

Decimal point is removed based on the number of digits after the decimal point. Here there are two digits after the decimal point. Remove it placing the hundred below the digit.
 $ 0.15 = \dfrac{{15}}{{100}} $

Since the percentage is for the hundredth denominator.
It can be written as –
 $ 0.15 = 15\% $

This is the required solution.

Note: Be careful while simplifying equations and always remember when its percentage is with respect to hundred. Convert the decimal point in the form of fraction. To convert decimal into fraction, place the decimal number over its place value. For example, for $ 0.2 $ the two is in the tenths place so that we place $ 2 $ over $ 10 $ to create the equivalent fraction i.e. $ \dfrac{2}{{10}} $ and similarly if there is two digits after decimal point, for $ 0.25 $ the $ 25 $ is in the hundredths place so that we place $ 25 $ over $ 100 $ to create the equivalent fraction i.e. $ \dfrac{{25}}{{100}} $ .
