Question

By what rational number should -9/25 be multiplied to get 3/5?​

Answer 1

To find:-

• Rational number

SolutioN:-

Let the rational number be 'x'.

According to question

$\implies \: x \times ( \frac{ - 9}{25} ) = \frac{3}{25}$

$\implies \: x = \frac{3}{25} \times \frac{25}{-9}$

$\implies \: x = \frac{1}{-3}$

Verification:-

$\implies \: x \times ( \frac{ - 9}{25} ) = \frac{3}{25}$

• Put x = 1/-3

$\implies \: ( \frac{1}{-3} ) \times ( \frac{ - 9}{25} ) = \frac{3}{25}$

• (-9) × 1 = -9 and 25 × (-3) = -75

$\implies \: (\frac{-9}{-75} )= \frac{3}{25}$

• Minus sign will get cut.
• 9 and 75 will cut with the table of 3. 9 will cut 3 times and 75 will cut 25 times.

$\implies \: \frac{3}{25} = \frac{3}{25}$

Therefore, Rational number is 1/-3.
