20.50 into a fraction is 41/2. Since 20 is already a whole number, there is no need to convert it. Since .50 is a decimal, I have to convert it to a fraction, which is 1/2. I end up with the mixed number 20 1/2. Since I need to convert it to a fraction, I have to simplify it. 20 1/2 written as a fraction greater than 1 is 41/2.

Answer:
Step-by-step explanation:
Total number of students who roller skated = 80
Number of students who roller skated with laser tag = 39
Number of students who roller skated with no laser tag = 80 - 39 = 41
Therefore, percentage of students who roller skated with no laser tag =
= 27%
Since, number of students who played laser tag = 85
Percentage of students who played laser tag =
= 55%
Total number of students who played no laser tag = 45% of 154 = 69
Number of students with no roller skates and no laser tag = 69 - 41 = 28
Percentage of students with no roller skates and no laser tag =
= 18%
Percentage of students who played with no rollers skates = (30 + 18)%
= 48%
Laser tag No laser tag Total
Roller skate 25% 27% 52%
No Roller skate 30% 18% 48%
Total 55% 45% 100%
The answer is 8 gram/cm^3
