Question

1,4 : 6,3= x : (−36) ?

Answer 1

\(\dfrac{x}{-36}=\dfrac{1.4}{3.6}\)

\(\Leftrightarrow x=\dfrac{-36\cdot1.4}{3.6}=-10\cdot1.4=-14\)

Answer 2

x=-8

Answer 3

1,4 : 6,3 = x : (-36)

<=> \(\dfrac{4}{63}=\dfrac{-x}{63}\)

<=> 4 . 63 = 63 . (-x)

<=> 252 = -63x

<=> \(x=\dfrac{252}{-63}=-4\)

Answer 4

x= -14
