Putting Numbers in Order of Size

Write these numbers in order, from smallest to largest:

0.531 0.098 0.14 0.0026 0.7 0.007 0.03

1) These are all between 0 and 1, so group them by the number of 0s as the start:

2 initial 0s: 1 initial 0: no initial 0s

0.0026 0.007 0.098 0.03 0.531 0.14 0.7

2) Once they are in groups, just order them by comparing the first non-zero digits.

( If the first digits are the same, look at the next digit along instead)

0.0026 0.007 0.03 0.098 0.14 0.531 0.7
