a, x = 1/-2 và y = -1/3
ta có : x = 1/-2 ⇔ x = -1/2 = -3/6
y = -1/3 = -2/6
Vì -3/6 < -2/6
⇒ x = 1/-2 > y = -1/3
b, x = -2/3 và y = 0
vì -2/3 là số âm
⇒ -2/3 < 0
⇒ x = -2/3 < y = 0
c, x = -0,125 và y = 1/-8
ta có : x = -0,125 = -125/1000 = -1/8
y = 1/-8 = -1/8
Vì -1/8 = -1/8
⇒ x = -0,125 = y = 1/-8
Đáp án:
Giải thích các bước giải:
a) Ta có : $x^{}$=$\frac{1}{-2}$=$\frac{-3}{6}$
$y^{}$=$\frac{-1}{3}$=$\frac{-2}{6}$
mà -3<-2
⇒$\frac{-3}{6}$<$\frac{-2}{6}$
⇒$\frac{1}{-2}$<$\frac{-1}{3}$
⇒$x^{}$<y
b) Ta có : $x^{}$=$\frac{-2}{3}$<$\frac{0}{3}$=0=y
⇒$x^{}$ <y
c) Ta có : $x^{}$=-0,125=$\frac{-125}{1000}$=$\frac{-1}{8}$=$\frac{1}{-8}$=y
⇒$x^{}$=y
