You have to compare the fractions:
There are several methods to compare fractions. I will use the conversion to a common denominator.
This is how you convert all the fractions to an equivalent form with common denominator.
The least common denominator is: 3 * 2^3 = 24
Original fraction equivalent fraction
2/3 2*8 / 3*8 = 16 / 24
7/8 7*3 / 8*3 = 21 / 24
1/2 1*12 / 2* 12 = 12 / 24
3/4 3*6 / 4*6 = 18 / 24
Now you can compare the fractions: 12/24 < 16/24 < 18/24 < 21/24.
So, you see that the greatest fraction is 21 /24, i.e. 7/8, and the answer is the day when 7/8 of the team practiced.
