Answer:

-24, -21, -19, -19, -19, -14, -13, -12, -7, -3, 2, 5, 6, 11, 11, 15

Step-by-step explanation:

Hey there!

To put the numbers in least to greatest form, you need to put the biggest numbers with a - sign in front of it

This means negative

Negative means below zero

Then after putting the big negative numbers, you put positive numbers going from smallest to largest

So the numbers in least to greatest is -24, -21, -19, -19, -19, -14, -13, -12, -7, -3, 2, 5, 6, 11, 11, 15
