Question
Identify the rational number that does not belong with the other three. Explain your reasoning
`(-5)/11, (-1)/2, (-4)/9, (-7)/3`
Advertisements
Solution
`(-5)/11 > (-11)/11 = -1, (-1)/2 > (-2)/2 = -1,`
`(-4)/9 > (-9)/9 = -1` and `(-7)/3 < (-3)/3 = -1`
Hence, `(-7)/3` is smaller than –1, whereas rest of the rational numbers are greater than –1.
