The statement on the bottom left is correct. (6 students studied for 20 to 24 hours)
8/1 x 2/3 = 16/3. 16/3 = 5 1/3
Okay this equation really says is what is 30% of 248.
So, lets convert 30% to a fraction, 3/10 which is easier to work with.
All you have to do now is get out a calculator and do 248 *3/10 (or .3) and get 74.4
So subtract 74.4 and get
173.6
