why is 2.50 m and 2.05 are not the same in distance

Answer 1

Which would you rather have?

$2.50 (two dollars and fifty cents)

or

$2.05 (two dollars and five cents)

An explanation:

2.50 means that the 5 is in the tenths place. 2.50 = 2 and 5/10

2.05 means that the 0 is in the tenths place. 2.05 = 2 and 0/10.
