Answer 2

`(21)/(2)`

Explanation:

The given number is 10.5.

We need to write the given number in the form of a/b.

Multiply an divide the given number by 10 to remove the decimal.

`10.5* (10)/(10)`

`(10.5* 10)/(10)`

`(105)/(10)`

It can be written as

`(5* 21)/(5* 2)`

Now cancel out common factors.

`(21)/(5)`

Therefore, the fraction form of given number is
`(21)/(2)`.
