Re-Test me over this question
-Mixed Numbers such as 2
1
2
must be entered as either a decimal, 2.5 or a fraction, 3/2.

-If a Decimal Answer does not fit in the space, it MUST be rounded AND contain 4 characters, including the decimal.
For example,
2
3
would be .667 while .666 would be incorrect and .67 would be incorrect

-Do NOT add a leading zero to a decimal, so 0.33 would be incorrect, while .33 would be correct.
