Answer: Hope this helps

Step-by-step explanation:The equation for finding the frequency of a sound wave given speed and wavelength is:

Speed = Wavelength * Frequency

Therefore, by algebra;

Frequency = Speed / Wavelenght

The given values are:

speed = 330 m/s

wavelength = 0.1 m

Therefore to solve for frequency:

Frequency = (330 m/s) / 0.1 m = 3.3 kHz

Therefore, the frequency of a sound wave at wavelength equals 0.1 m 3.3 kHz.

Which is equivalent to 4:52 ​
Alex787 [66]

<em>I think the best answer is:</em>

\frac{1}{13}

Explanation Below.

This is a proper fraction once the absolute value of the top number or numerator (4) is smaller than the absolute value of the bottom number or denomintor (52).

The fraction \frac{4}{52}  can be reduced.

We will use the Greatest Common Factor (GCF) method to simplify it.

The GCF is the largest number between which two or more numbers can be divided evenly.

To find the GCF we list the the numerator and denominator factors (*) then we find the largest number that is repeated in both lists:

* The factors of 4 are 1,2,4;

* The factors of 52 are 1,2,4,13,26,52.

We can see that the GCD is 4 because it is the largest number by which 4 y 52 can be divided without leaving any residue.

To reduce this fraction, simply divide the numerator and denominator by 4 (the GCF).

So, \frac{4}{52} = 4 ÷ 4

-------------------------

52 ÷ 4 ≈ \frac{1}{13}

The factors are numbers that multiply each other to get another number. For example, 2 and 3 are factors of 6, because by multiplying them you get 6.

Goodluck!!
