To solve these problems, we will use the concept of percentages.

1. Parliament sits for 8 months of the year:
   - Total months in a year = 12
   - Percentage of the year that parliament sits = (8/12) * 100

2. There are 30 students in a class, 12 of whom are boys:
   - Total students = 30
   - Boys = 12
   - Girls = Total students - Boys
   - Percentage of girls in the class = (Girls / Total students) * 100

3. There are 28 players in a soccer squad, 75% of whom arrived for practice:
   - Total players = 28
   - Percentage of players who arrived = 75%
   - Number of players who arrived = (75/100) * Total players
   - Number of players missing = Total players - Number of players who arrived

Let's calculate the answers to these problems.
Calculate the value by following steps:
- step0: Calculate:
  $$\left(\frac{8}{12}ight)	imes 100$$
- step1: Reduce the fraction:
  $$\frac{2}{3}	imes 100$$
- step2: Multiply:
  $$\frac{2	imes 100}{3}$$
- step3: Multiply:
  $$\frac{200}{3}$$
1. Parliament sits for 8 months of the year, which is equivalent to $$ \frac{200}{3} $$ or approximately 66.67% of the year.

2. There are 30 students in a class, 12 of whom are boys. The number of girls in the class is 30 - 12 = 18. The percentage of girls in the class is $$ \frac{18}{30} 	imes 100 = 60\% $$.

3. There are 28 players in a soccer squad, 75% of whom arrived for practice. The number of players who arrived is $$ 75\% 	imes 28 = 21 $$. The number of players missing is 28 - 21 = 7.

Therefore, the answers are:
1. Parliament sits for approximately 66.67% of the year.
2. The percentage of girls in the class is 60%.
3. 7 players were missing from the soccer squad.
1. Parliament sits for about 66.67% of the year. 2. 60% of the class are girls. 3. 7 players were missing from the soccer squad.
