3. How many beats are in each measure?

2 beats

4 beats

8 beats

In music, a measure is a unit of time that contains a specific number of beats. The question is asking how many beats are in each measure. The correct answer is 4 beats, which means that each measure in this particular piece of music is divided into four equal parts. This is a common time signature in music, known as 4/4 time or common time, where each measure consists of four beats and the quarter note receives one beat.

4. If there are 48 beats in the whole song, how many measures are in a song, and what operation do you use to solve this problem?

10 measures, division

8 measures, multiplication

12 measures, division

To determine the number of measures in a song, we need to divide the total number of beats in the song by the number of beats in each measure. Since the question states that there are 48 beats in the whole song, we need to divide this by the number of beats in each measure. Therefore, the correct answer is 12 measures, using division.

Explanation

To determine the number of measures in a song, we need to divide the total number of beats in the song by the number of beats in each measure. Since the question states that there are 48 beats in the whole song, we need to divide this by the number of beats in each measure. Therefore, the correct answer is 12 measures, using division.

5. If you play 40 beats only, how many measures do you play?

6 measures

8 measures

10 measures

If you play 40 beats, and assuming each measure has 4 beats, then you can calculate the number of measures by dividing the total beats (40) by the beats per measure (4). Therefore, 40 divided by 4 equals 10 measures.

Explanation

If you play 40 beats, and assuming each measure has 4 beats, then you can calculate the number of measures by dividing the total beats (40) by the beats per measure (4). Therefore, 40 divided by 4 equals 10 measures.

6. How many beats do you play if you play 3 measures?

12 beats

10 beats

16 beats

If you play 3 measures, and each measure has 4 beats, then the total number of beats would be 4 beats per measure multiplied by 3 measures, which equals 12 beats.

Explanation

If you play 3 measures, and each measure has 4 beats, then the total number of beats would be 4 beats per measure multiplied by 3 measures, which equals 12 beats.

7. How much of the music do you play in fraction if you play only 8 measures?

6/16 or 3/8

8/12 or 2/3

10/16 or 5/8

The question asks for the fraction of music played if only 8 measures are played. The correct answer is 8/12 or 2/3. This means that out of a total of 12 measures, 8 measures are played, which can be simplified to 2/3.

Explanation

The question asks for the fraction of music played if only 8 measures are played. The correct answer is 8/12 or 2/3. This means that out of a total of 12 measures, 8 measures are played, which can be simplified to 2/3.

8. If you play 6 measures and your partners play 3 measures, how many beats do you play in all?

16 beats

20 beats

36 beats

If you play 6 measures and your partners play 3 measures, it means that you are playing twice as many measures as your partners. Since each measure typically consists of 4 beats, you would be playing 6 x 4 = 24 beats. Therefore, the correct answer is 36 beats.

Explanation

If you play 6 measures and your partners play 3 measures, it means that you are playing twice as many measures as your partners. Since each measure typically consists of 4 beats, you would be playing 6 x 4 = 24 beats. Therefore, the correct answer is 36 beats.

9. How much of the music do you play in fraction if you play only 4 measures?

4/12 or 1/3

1/4

4/16

The correct answer is 4/12 or 1/3 because if you play only 4 measures out of a total of 12 measures, you are playing 1/3 of the music. This can be calculated by dividing the number of measures played (4) by the total number of measures (12), resulting in a fraction of 4/12 or simplified as 1/3.

Explanation

The correct answer is 4/12 or 1/3 because if you play only 4 measures out of a total of 12 measures, you are playing 1/3 of the music. This can be calculated by dividing the number of measures played (4) by the total number of measures (12), resulting in a fraction of 4/12 or simplified as 1/3.

10. If you play 3 measures and your partner plays 5 measures, how much of the music do you play in all in fraction?

10/16 or 5/8

8/12 or 2/3

8/16 or 2/4 or 1/2

In this scenario, if you play 3 measures and your partner plays 5 measures, the total number of measures played by both of you is 8. To find the fraction of the music you play, you need to divide the number of measures you play by the total number of measures. Therefore, the fraction is 3/8. However, the answer given is 8/12 or 2/3, which is incorrect.
