Question

How do we write $4.5$ as a fraction?

Answer 1

Hint: Fraction is the term expressed in the form of numerator upon the denominator. While converting the decimal in the form of fraction, first of all count the number of digits after the decimal point. First of all remove decimal point and place the number of zeros in the denominator and simplify for the resultant required value.

Complete step-by-step answer:
Take the given term: $4.5$
As the given number is in decimal and it terminates after its first decimal so it can be re-written as the fraction where denominator will be ten.
$4.5 = \dfrac{{45}}{{10}}$
Find factors of the term in the above expression –
$4.5 = \dfrac{{9 \times 5}}{{2 \times 5}}$
Common term from the numerator and the denominator cancels each other and therefore remove from the numerator and the denominator of the above expression –
$4.5 = \dfrac{9}{2}$
This is the required expression.
So, the correct answer is “$ \dfrac{9}{2}$”.

Note: Remember the difference between the fraction and the percentage. Percentage is the term where the denominator is always hundred. Be good in multiples and division and always remember that the common factors from the numerator and the denominator cancels each other. We can “n” number of equivalent fractions for any fraction.
