Question

Choose the smallest decimal number from the following

• A. $2.15$
• B. $2.1235$
• C. $2.123$
• D. $2.132$

Answer 1

Answer: (C)

$2.123$

To compare decimal numbers, we start from right and compare the digits

First and second digits of all the numbers are same

So, compare third digit and we get $2.123$ and $2.1235$ as smallest

Now, from $2.123$ and $2.1235$, $2.123$ is smallest as there is $5$ in the other number at 5th digit place

So, in the given options smallest number is $2.123$.

Hence, correct answer is option C.
