Question

 

Answer 1

\(\dfrac{12}{-24}=\dfrac{-1}{2};\dfrac{-39}{75}=\dfrac{-13}{25};\dfrac{132}{-264}=\dfrac{-1}{2}.\)

Answer 2

\(\dfrac{12}{-24}=\dfrac{-12}{24}=\dfrac{-12:12}{24:12}=\dfrac{-1}{2}\\ \dfrac{-39}{75}=\dfrac{-39:3}{75:3}=\dfrac{-13}{25}\\ \)

Answer 3

\(\dfrac{12}{-24}=\dfrac{-1}{2}\)

\(\dfrac{-39}{75}=\dfrac{-13}{25}\)

\(\dfrac{132}{-264}=\dfrac{-1}{2}\)

Answer 4

\(\dfrac{12}{-24}=\dfrac{12\div12}{-24\div12}=\dfrac{1}{-2}\)

\(\dfrac{-39}{75}=\dfrac{-39\div3}{75\div3}=\dfrac{-13}{25}\)

\(\dfrac{132}{-264}=\dfrac{132\div132}{-264\div132}=\dfrac{-1}{2}\)

Answer 5

\(\dfrac{12}{-24}\) = \(\dfrac{-12}{24}\) = \(\dfrac{-12:12}{24:12}\) = \(\dfrac{-1}{2}\)

\(\dfrac{-39}{75}\) = \(\dfrac{-39:3}{75:3}\) = \(\dfrac{-3}{25}\)

\(\dfrac{132}{-264}\) = \(\dfrac{-132}{264}\) = \(\dfrac{-132:132}{264:132}\) = \(\dfrac{-1}{2}\)

Answer 6

12/-24=-1/2

-39/75=-13/25

132/-264=-1/2
