Answer 2

The answer is 5/4

GIVEN

The product of two rational numbers is 1

One of the number is 4/5

TO FIND

The other number

SOLUTION

We can simply solve the above problem as follows;

Let the unknown number be x

Other number = 4/5 (Given)

It is given that,

The product of two numbers is 1

The algebraic equation thus formed is as follows;

$x \times \frac{4}{5} = 1$

To solve for x the number multiplied to x is divided by the product.

Therefore;

$x = \frac{1}{ \frac{4}{5} }$

We know that when the fractions are divided, The denominator is multiplied to the dividend

Therefore;

$\frac{1}{ \frac{4}{5} } = \frac{1 \times 5}{4} = \frac{5}{4}$

Hence, The answer is 5/4
