Answer 2

Given:

An expression.

$\frac{25}{14} \times \: multiplicative \: inverse \: of \: \frac{5}{7}$

To find:

The value of the given expression.

Solution:

To answer this question, first of all, we should know that the multiplicative inverse of a number a/b is b/a.

This means that the multiplicative inverse is the number or fraction which is multiplied to a given number so that result becomes 1.

Now,

proceeding to the solution,

the multiplicative inverse of 5/7 is 7/5.

Now, according to the question,

$\frac{25}{14} \times \frac{7}{5}$

$= \frac{5}{2}$

Hence, the value of the given expression is 5/2.
