Joanna, Dana and Tracy shared some trail mix. Joanna ate 0.125 pound of trail mix, Dana ate 0.1 pound and Tracy ate 0.12 pound of trail mix. List the friends in order from least to greatest amount of trail mix eaten

We are given the following values:

0.125 pound

0.1 pound

0.12 pound

All values start with the same number which is 0.1, therefore the 0.1 is the smallest.

Next the two values are followed by 0.12, so 0.12 is the next smaller number.

So the largest number is 0.125.

Arranging from least to greatest amount of trail mix eaten:
