When A dotted half note has beats when the time signature is 44.?

In a 4/4 time signature, a dotted half note receives three beats. The dot adds half of the note's original value to itself, so a half note (which is worth two beats) plus the additional beat from the dot totals three beats. This means that in a measure of 4/4, a dotted half note would take up most of the measure, leaving one beat remaining for other notes or rests.
