For this case we can make the following rule of three:
75 -----------------> 100%
58 -----------------> x
From here, we clear the value of x.
We have then:
[tex] x = (\frac{58}{75}) * (100)
x = 77.33333333
[/tex]
Rounding to the nearest hundredth we have:
[tex] x = 77.33 [/tex]%
Answer:
58 is 77.33% of 75
