Answer 1

Hint: Use the concept of roman numbers and find the suitable Roman numeral for the given number.
* Roman numeral: A numeral in a system of notation that is completely based on the ancient roman system is called a roman numeral.

Complete step-by-step answer:
We have to find the Roman numeral for the given number i.e. $48$
Since we know Roman numerals follow the ancient Roman system. So we convert the given number i.e. 48 according to the ancient Roman system.
Since we know \[10 < 48 < 50\]
So from the ancient Roman system we can say \[X < 48 < L\]
Since $X$ stands for $10$
\[ \Rightarrow \] $XX$ stands for $20$
\[ \Rightarrow \] $XXX$ stands for $30$
\[ \Rightarrow \] $XL$ stands for $40$ …………………...… (1)
Now we look at the counting of roman numbers from the beginning.
Since $I$ - stands for $1$
\[ \Rightarrow \]$II$ stands for $2$
\[ \Rightarrow \]$III$ stands for $3$
\[ \Rightarrow \]$IV$ stands for $4$
\[ \Rightarrow \]$V$ stands for $5$
\[ \Rightarrow \]$VI$ stands for $6$
\[ \Rightarrow \]$VII$ stands for $7$
\[ \Rightarrow \]$VIII$ stands for $8$ …………………….… (2)
From equations (1) and (2)
We can combine the number $48$ and write in roman form as $XLVIII$

\[\therefore \]The Roman numeral for the number 48 is XLVIII.

Note: General notations to be kept in mind for following ancient Roman numeral system are:
I - stands for 1
V- stands for 5
X- stands for 10
L- stands for 50
C- stands for 100
