For this case, we first look for the number of blonde girls.
We have then:
We are now looking for the percentage of the class with blonde hair.
For this, we make the following rule of three:
30 --------------> 100%
4.25 -----------> x
From here, we clear the value of x.
We have then:
Answer:
14.2% of the class are blonds

Hey Aarya!
If we `scale` both the numerator and denominator by the same value, then we can create other equivalent fractions. By scale I mean: Multiply both the top and bottom of the fraction by the same value.
So here is one we can try.
Let's multiply numerator and denominator by 3.
Yay we did it! We found another fraction which is equivalent to 3/8.
