Question

what is the equivalent rational number for -15 by 36 with denominator 12

Answer 1

$\textbf{Answer}$

Given rational number = - (15/36)

Lets suppose that the equivalent rational number to the given number,with denominator 12 is $\textbf{- X/12.}$


$\textbf{According to the question,}$

-15 : 36 = -X : 12

=> (15/36) = (X/12)

=> X/12 = 15/36

=> X = (15×12)/36

=> X = (2×2×3×3×5)/(2×2×3×3)

=> X = 5

So the required equivalent ration is -X/12,and value of X is 5,

=> $\textbf{-5/12 is equivalent rational number}$ to $\textbf{the rational number -15/36.}$


$\textbf{Hope My Answer Helped}$

Answer 2

Given rational number = - (15/36)

Lets suppose that the equivalent rational number to the given number,with denominator 12 is \textbf{- X/12.}- X/12. 


\textbf{According to the question,}According to the question, 

-15 : 36 = -X : 12

=> (15/36) = (X/12)

=> X/12 = 15/36

=> X = (15×12)/36

=> X = (2×2×3×3×5)/(2×2×3×3)

=> X = 5

So the required equivalent ration is -X/12,and value of X is 5,

=> \textbf{-5/12 is equivalent rational number}-5/12 is equivalent rational numberto \textbf{the rational number -15/36.}the rational number -15/36.
