Answer:
If we have two quantities x and y, an inverse variation can be written as:
y = k/x
where k is a constant.
Now, we know that for this particular inverse variation the point (3, -4) is included.
Then we can find the value of k by replacing the values of the point in the general equation:
-4 = k/3
k = -4*3 = -12
Then our inverse variation is:
y = -12/x.
Then if we want another point that also does belong in the inverse variation, we can give x a different value and solve the equation for y.
For example, if x = 1
y = -12/1 = -12
then the point (1, -12) also does belong in the inverse variation.
if x = 6
y = -12/6 = -2
the point (6, -2) also does belong to the inverse variation

<h2>
Hello!</h2>
The answer is:
The fraction is equivalent to 80%.
<h2>
Why?</h2>
To solve the problem, we need to remember that if we want to convert from numbers to percentual values, we need to multiply the given number by 100.
So, if we have the fraction four-fifths which is:
If we need to convert it to percent, we need to multiply it by 100:
Hence, we have that the fraction is equivalent to 80%.
Have a nice day!
