Fill in the blanks-
Something that cannot be divided is called-----.

Hint: Here in the given question we need to solve the statement, which says that what is called, which cannot be divided, here we should know that if a number is divisible then it will be completely divided by a specific number and does not give any remainder.

Complete step by step answer:
Here in the given question we need to find the answer for an statement which says that if what is called, if it is not divisible, here we know that divisibility means if a number is completely divisible, without any remainder, and the number which is not divisible will have remainder with it on dividing with any specific number and thus called indivisible number.
Here the answer for the question is indivisible number.
For example:
\[ \Rightarrow \dfrac{{5.5}}{4}\]
Here 5.5 will be an indivisible number, because 5.5 dividing by four it will give a remainder and will not be completely divisible.

Note: Here the statement type question is given, and to solve this question we need to find the assertion and reason behind that, without knowing the reason we cannot solve the statement type question.
