đáp án là \(\dfrac{k}{-5}\)

Chúc bạn học tốt

\(\dfrac{k}{-5}\)

x 5 (x ∈ Z)

\(a.\\ 5:\left(-13\right)=\dfrac{-5}{13}\)

\(b.\\ x:3=\dfrac{x}{3}\)

\(c.\\ 6=\dfrac{6}{1}\)

\(d.\\ 1.25=\dfrac{5}{4}\)

a. 3 : 11 = \(\dfrac{3}{11}\)

b. -4 : 7 = \(\dfrac{-4}{7}\)

c 5 : ( -13)  = \(\dfrac{5}{-13}=\dfrac{-5}{13}\)

d x : 3 \(\left(x\in z\right)\)

= \(\dfrac{x}{3}\)

\(a,3:11=\dfrac{3}{11}=\dfrac{-3}{-11}\\ b,-4:7=\dfrac{-4}{7}=\dfrac{4}{-7}\\ c,5:\left(-13\right)=\dfrac{5}{-13}=\dfrac{-5}{13}\\ d,x:3=\dfrac{x}{3}=\dfrac{-x}{-3}\)
