Question

early musical notation​

Answer 1

Explanation:

q should have any factor or multiple of 10 that is q=2^{x} \times 5^{y}q=2

x

×5

y

where x and y are positive integers.

Given:

\frac{p}{q}

q

p

is the rational number

To find:

The condition of q so that the decimal representation of \frac{p}{q}

q

p

is terminating

Solution:

Given, \frac{p}{q}

q

p

is a rational number where q not equal to 0.

So, for \frac{p}{q}

q

p

to be a terminating decimal, q should have any factor or multiple of 10.

This can be represented in the order of \bold{q=2^{x} \times 5^{y}}q=2

x

×5

y

, where both x and y are positive integers.

So, q must be any factor or multiple of 10 expressed in the form of 2^{x} \times 5^{y}2

x

×5

y

, for a fraction

\bold{\frac{p}{q}}

q

p

to be a terminating fraction.

Answer 2

Answer:

Here

Explanation:

The earliest form of musical notation can be found in a cuneiform tablet that was created at Nippur, in Babylonia (today's Iraq), in about 1400 BC. The tablet represents fragmentary instructions for performing music, that the music was composed in harmonies of thirds, and that it was written using a diatonic scale.
