What is this from least to greatest

-8.2,0.4,-2 1/2,2.4

i got 0.4,-2 1/2,2.4.-8.2

You answer is wrong because the negative numbers are less then positive numbers, and the higher the positive value of a negative number, the smaller is the number.

First, express all the numbers as decimals:

-2 1/2 = - 2.5

From least to greatest, we have: - 8.2, - 2 1/2, 0.4, 2.4
