A half of a class and a half of a student got A on a test. If yet another student got an A, then two-thirds of the class would h
svlad2 [7]

Answer:

6 students.

Step-by-step explanation:

let the number of students in class be<em> x</em>

Since Half of the class represents half of the students, therefore

Number of student who got A in test = \frac{x}{2}

Now if one more student got A in test then the number of students who got A in test will be \frac{x}{2} +1

Now according to equation,

\frac{2x}{3} = \frac{x}{2} +1

\frac{2x}{3} - \frac{x}{2} = 1

Further solving

\frac{4x-3x}{6} = 1

x = 6

Hence the total number of students in class is 6.
