The multiplicative inverse of a number can also be defined as the reciprocal of that number.
In Mathematics, the multiplicative inverse of a number x is given as:
[tex]\frac{1}{x}[/tex].
The multiplicative inverse of [tex]2\frac{1}{2}[/tex] is [tex]\frac{2}{5}[/tex].
In the above question, we are given the fraction [tex]2\frac{1}{2}[/tex]. We convert the mixed fraction to an improper fraction. Hence:
[tex]2\frac{1}{2}[/tex] = [tex]\frac{5}{2}[/tex]
Therefore, the multiplicative inverse of [tex]\frac{5}{2}[/tex] is :
[tex]\frac{5}{2}[/tex] = [tex]\frac{2}{5}[/tex]
