0.58, 0.8, –2.16, –2.6, 5.1
B
–2.16, –2.6, 0.8, 0.58, 5.1
C

D
–2.6, –2.16, 0.58, 0.8, 5.1

Explanation

Negative numbers are less than positive numbers, and among negatives the number farther from zero is smaller. So –2.6 < –2.16. Among the positive numbers, 0.58 < 0.8 < 5.1. The numbers from least to greatest are –2.6, –2.16, 0.58, 0.8, 5.1, which is choice D.
