20/40 vision means that the test subject sees at 20 feet what a normal person sees at 40 feet. Another way of saying this is that a person with 20/40 vision has vision that is only half as good as normal-or, objects must be at half the normal distance for him to see them.

The compromise was to count only 3/5 of the slaves in determining how many representatives to allocate to each state. ( how the slave population would be counted ) The Three-Fifths Compromise was made in the US Constitutional Convention. Slave states wanted to count their entire slave population in determining how many representatives each state had in the House of Representatives.
