To determine which fraction is equivalent to 0.76 miles, we need to find a fraction that represents the same portion of a whole as 0.76 represents of 1.
To do this, we can convert 0.76 to a fraction.
0.76 can be written as 76/100 because 0.76 is the same as 76 hundredths.
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 4.
76/100 simplifies to 19/25.
Therefore, the fraction equivalent to 0.76 miles is 19/25.

To find the fraction of students at Lamar High School who are girls in the choir, we need to multiply the fraction representing the proportion of girls in the school (2/3) by the fraction representing the proportion of girls in the choir (2/3).
First, let's multiply the numerators: 2 * 2 = 4.
Then, let's multiply the denominators: 3 * 3 = 9.
So, the fraction of students at Lamar High School who are girls in the choir is 4/9.
Therefore, the correct answer is E) 4/9.
