There are ten-tenths of a mile in 1 mile since a single mile contains all the parts into which it is divided, as illustrated by HomeschoolMath.net’s description of fractions. An often-repeated math corollary is that any whole is equal to all its parts taken together.
When taking into consideration more than ten-tenths, such as eleven-tenths or fourteen-tenths, for example, the distance formed by the parts is greater than a mile because the units add up to more than the whole. If fewer than ten-tenths are taken, such as two-tenths or nine-tenths, the resulting distance is inevitably less than a mile.
