How many beats are in EACH of these measures (if the quarter note gets one beat)?

To determine the number of beats in each measure when the quarter note gets one beat, you need to look at the time signature. For example, in 4/4 time, there are four beats per measure; in 3/4 time, there are three beats; and in 6/8 time, there are six beats (though it's often counted in two groups of three). Each measure's beat count corresponds to the numerator of the time signature, representing how many quarter note beats fit into the measure.
