Answer 2

Given,

The given numbers are :

$2 \: \: \: and \: \: \: \frac{5}{8}$

To find,

The multiplicative inverses of the given numbers.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now, product of any number and its multiplicative inverse is always equal to 1.

Let, the multiplicative inverse of 2 = x

According to the previously mentioned mathematical property of multiplicative inverse.

$2 \times x = 1$

$x = \frac{1}{2}$

Similarly,

Let, the multiplicative inverse of ⅝ = y

$\frac{5}{8} \times y = 1$

$5y = 8$

$y = \frac{8}{5}$

Hence, the multiplicative inverse of 2 is ½ and multiplicative inverse of ⅝ is ⁸/₅
