Jack is learning to play piano. He knows that a piano has 88 keys and that there are 12 unique keys in each group called octave. How many complete octaves are on a piano?

Respuesta :

There are seven full Octaves on a piano with 88 keys 

Answer:

7 octaves

Step-by-step explanation:

Total number of keys in piano = 88 keys

Numbers of keys in each group called octave= 12 unique keys

We have to find the number of complete octaves on piano

Number of octaves consists of 12 keys= [tex]\frac{Total number of keys}{12}[/tex]

Number of octaves consists of 12 keys= [tex]\frac{88}{12}[/tex]

Number of octaves consists of 12 keys= 7 octaves

Hence, the correct answer is 7 octaves
