Question

Which of the following is a rational number but not a fraction?

• A. 4
• B. -4
• C. $\frac{1}{3}$
  
• D. $\frac{5}{2}$
  

Answer 1

The correct option is B -4

As we noticed that all the given options are rational numbers, because rational numbers are in the form of $\frac{p}{q}$, where $p$ and $q$ are integers and $q\ne 0$.

And we already know, fractions are in the form of $\frac{a}{b}$, where $a$ and $b$ are whole numbers and $b\ne 0$.

$4$, $\frac{1}{3}$ and $\frac{5}{2}$ can be represented in the form of fraction but $-4$ can not be represented in the form of fraction because if we write $-4$ as $\frac{-4}{1}$, numerator is $-4$, which is not a whole number.

Hence, B is correct option.
