Answer 2

Given :-

• Product of two numbers is -3/4.
• One number is 5/4

To find :- Other number.

$\large\bf\underline\blue{SolutioN:-}$

Let the other number be 'x'

So, According to question

$⇢ \frac{5}{4} - x = \frac{ - 3}{4}$

$⇢-x = \frac{ - 3}{4} - \frac{5}{4}$

$⇢ - x = \frac{ - 3 - 5}{4}$

$⇢ - x = \frac{ - 8}{4}$

$⇢ - x = - 2$

• Minus cancelled by minus . So,

Value of x = 2

Verification:-

$⇢ \frac{5}{4} - x = \frac{ - 3}{4}$

• Put x = 2

$⇢ \frac{5}{4} - 2 = \frac{ - 3}{4}$

$⇢ \frac{5-8}{4} = \frac{ - 3}{4}$

$⇢ \frac{-3}{4} = \frac{ - 3}{4}$

Hence other number is 2.
