To find out how much time Adelina spent at the tutoring session, you can multiply the fraction of the session she attended by the total time of the session.
The total time spent on reviewing math problems is 2/3 of an hour.
Adelina attended 3/4 of that time.
So you perform the following multiplication to find the time Adelina spent:
2/3 hour (time spent on math problems) * 3/4 (portion Adelina attended) = 6/12 hour
After performing the multiplication of the numerators (2*3) and the denominators (3*4), you get 6/12.
You can simplify 6/12 by dividing both the numerator and the denominator by their greatest common divisor, which is 6.
6/12 simplified is 1/2.
Therefore, Adelina spent 1/2 hour, or 30 minutes, at the tutoring session.
