Answer 2

Question:

Express 3/5 as rational number with denominator -20.

Answer:

$Rational \: number \: is \: \boxed{ \frac{ - 12}{20}}$

Step-by-step explanation:

$Now \: \frac{3}{5}$

$Numerator = 3$

$Denominator = 5$

Rationalising numerator and denominator,

Multiplying numerator with - 4

$Numerator = 3 \times - 4$

$Numerator = - 12$

Multiplying denominator with 4

$Denominator = 5 \times 4$

$Denominator = 20$

$Rational \: number \: is \: \boxed{ \frac{ - 12}{20}}$

$Therefore \: rational \: number \: is \: \boxed{ \frac{ - 12}{20}}$
