Answer: 
of an hour.
Step-by-step explanation:
1. You know that it is from 3:12 p.m. (48 minutes before 4:00 p.m.) to 4:30 p.m. (30 minutes after 4:00 p.m.)
2. Therefore, you must make the following addition:
This is 78 minutes out of 1 hour (60 minutes).
3. Therefore, you have the following fraction:
4. Now, you must reduce the fraction:
5. The answer is 13/10 on an hour.
The answer is 12/5

Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Total number of students = 200
Number of females = 110
Number of students under the age of 21 years of age = 125
Number of males under the age of 21 years or older = 45
So, it becomes
Males Females Total
21 years 45 80 125
21 years or older 45 30 75
Total 90 110 200
So, Probability that a female student age 21 or older is selected is given by
Hence, Option 'a' is correct.

Answer:
4 18/12 - (2 8/12+ 3/12)= 2 7/12
Step-by-step explanation:
First you want to know that you want to subtract the bird seed Jackie got (2 2/3 and 1/4) by the total Jackie bought (5 1/2).
Now set up the equation as 5 1/2 - (2 2/3+ 1/4). Now you need to realize that the fractions are not the same and need to be changed to similar denominators. 2 can be changed to any even denominator so it matters less to what we change it to, so let's focus on the bird seed Jackie used and convert it. 2/3 and 1/4 can be changed into 12's so multiply on the numerator and denominator to get these values. 2/3 would then become 8/12 and 1/4 would become 3/12. 1/2 would then also become 6/12.
Now that we have changed the fractions you want to change the expression to 5 6/12 - (2 8/12+ 3/12). Now add the values in the parentheses to get 5 6/12 - (2 11/12). Now to make this easier add more 12's to 5 6/12 by putting it to 4 18/12. the new equation will be 4 18/12 - 2 11/12, finally subtract from from the same types of numbers: 4-2= 2 18/12-11/12= 7/12. The answer would be 2 7/12.
