Question

Which set of numbers below is in the correct order from least to greatest?
−2.5<234<−215<2.1

−215<234<2.1<−2.5

−2.5<−215<2.1<234

2.1<−215<−2.5<234

Answer 1

The third choice. In increasing order the numbers are
−2.5 < −2.15 < 2.1 < 2.34,
so the option −2.5 < −215 < 2.1 < 234 (interpreting −215 as −2.15 and 234 as 2.34) is correct.
