Explanation:
If the amount of change due to rounding is the same for both numbers, the original difference and the difference of rounded values will be the same. This will always be the case if the hundredths digits are the same to start with.
Example:
A = 0.56 ⇒ C = 0.6
B = 0.66 ⇒ D = 0.7
__
B - A = 0.66 -0.56 = 0.10
D - C = 0.7 -0.6 = 0.10 . . . . . same as B - A, ∴ Dominic is incorrect.
