Answer:
C
Explanation:
On a number line, larger numbers are toward the right, and smaller ones are toward the left.
They both are negative numbers, which means that they are smaller than 0, therefore, they will both be on the left side. The means A and C are not the right answers.
Because -⁸/₁₈ is larger than -¹⁷/₂₇, it will be further right, which makes C the correct answer.
