In 3/4 time, how many beats does a quarter rest
last for?

The time signature 3/4 means that a quarter note gets one beat and there are 3 beats per measure. The first measure has 3 quarter notes, and each one gets one beat. You can count them as "one two three." The second measure has a half note, which gets 2 beats, followed by a quarter note, which gets one beat.

the answer is true : 0)

you didnt add any sort of groups or any options, you can edit it and then people can try to answer now its kinda hard.

hope this gives you a heads up why you arent answered. : d

have a great rest of your day!
