Answer:

\frac{15}{4}

Can also be written as the following,

3\frac{3}{4}

Step-by-step explanation:

First, set up the given problem,

\frac{3}{4} ÷ \frac{1}{5}

In order to divide two fractions, one must take the reciprocal of the second fraction and then change the multiplication sign to a division sign. Apply this technique to the given problem,

\frac{3}{4} ÷ \frac{1}{5}

\frac{3}{4} * \frac{5}{1}

Multiply,

\frac{15}{4}

Convert to a mixed number. To convert an improper fraction to a mixed number, one must divide the numerator (number on top of a fraction) by the denominator (number under the fraction bar), write the whole value to the left of the fraction, and the remainder of the division in place of the numerator.

3\frac{3}{4}

Calculate the frequency of a wave with a speed of 130 m/s and a wavelength of 2.5
denis23 [38]

Answer:

  52 Hz

Step-by-step explanation:

We can divide the speed by the wavelength to find the number of waves propagated in one second:

  (130 m/s)/(2.5 m/wave) = 52 waves/s

The SI unit of frequency is the Hertz, equal to one cycle per second.

The frequency of this wave is 52 Hz.

_____

<em>Additional comment</em>

The use of the unit Hz to signify frequency was adopted in 1933, but did not replace the unit "cycles per second" (CPS) until a number of years later.

I need help with this question
nata0808 [166]

I don't know if you've learnt this, but there's something called the KFC rule (you use it when dividing fractions), so k basically stands for keep (so you keep the first fraction), f stands for flip (so you flip the second fraction) and c stand for change (you change the division sign to a multiplication sign)

So you get

5/20*11/5

55/100

which is 11/20

so, an answer of 11/20 would make Quintin correct
