Jamie bought a roll of tape that measured 1 meter in length. He used 1/4 of the tape to wrap his hockey stick. He used 1/8 of the tape to fix a whole in his hockey bag. What fraction of the tape was left?
Correct Answer
C. 5/8 meter
Explanation
Jamie used 1/4 of the tape to wrap his hockey stick and 1/8 of the tape to fix a hole in his hockey bag. To find the fraction of tape left, we need to subtract the fractions used from the whole roll of tape. 1/4 + 1/8 = 3/8 of the tape was used. Therefore, the fraction of tape left is 1 - 3/8 = 5/8 meter.

Mrs. Smith bought 24 markers. 7 markers had green ink. 15 markers had red ink. The rest had black ink. What fraction of the markers had black ink?
Correct Answer
A. 1/12 had black ink
Explanation
To find the fraction of markers with black ink, you need to determine how many markers had black ink out of the total number of markers, which is 24 in this case.
You know that 7 markers had green ink and 15 had red ink, so to find the number with black ink:
Total markers - (Markers with green ink + Markers with red ink) = Markers with black ink
24 - (7 + 15) = 24 - 22 = 2 markers had black ink.
So, 2 out of the 24 markers had black ink. To express this as a fraction, you can write it as 2/24, which can be simplified to 1/12. Therefore, 1/12 of the markers had black ink.

Mark and Chris had an equal number of chocolate bars. Mark ate 1/5 of his chocolate bars. Chris ate 1/4 of his chocolate bars. Who has more chocolate bars left?
Correct Answer
A. Mark
Explanation
Mark has more chocolate bars left because he ate a smaller fraction of his chocolate bars compared to Chris. Mark ate 1/5 of his chocolate bars, while Chris ate 1/4 of his chocolate bars. Since 1/5 is smaller than 1/4, Mark has more chocolate bars left.

40 students made the student council. 5/8 of the students were girls. How many boys made student council?
Correct Answer
B. 15 boys
Explanation
If 5/8 of the students were girls, then 3/8 of the students must be boys. Since the total number of students in the student council is 40, we can calculate the number of boys by multiplying 3/8 by 40. This gives us (3/8) * 40 = 15 boys. Therefore, the correct answer is 15 boys.

Holly completed the race in 2 1/2 hours. Mary completed the same race in 3 1/4 hours. How much longer did Mary take to complete the race than Holly?
Correct Answer
B. 3/4 hour
Explanation
Mary took 3 1/4 hours to complete the race, while Holly took 2 1/2 hours. To find out how much longer Mary took, we need to subtract Holly's time from Mary's time. When we subtract 2 1/2 hours from 3 1/4 hours, we get 3/4 hour. Therefore, Mary took 3/4 hour longer than Holly to complete the race.

Hank went to the cider mill. The cost for one pound of apples is 1 1/2 dollars. How much would it cost for 3 pounds of apples?
Correct Answer
C. 4 1/2 dollars
Explanation
Hank went to the cider mill and wants to buy 3 pounds of apples. The cost for one pound of apples is 1 1/2 dollars. To find the total cost, we need to multiply the cost of one pound by the number of pounds. 1 1/2 dollars multiplied by 3 gives us 4 1/2 dollars, which is the total cost for 3 pounds of apples. Therefore, the answer is 4 1/2 dollars.

Lydia ate 4/5 of a pizza. Mark ate 1/10 of a pizza. How much pizza did they eat all together?
Correct Answer
C. 9/10 of a pizza
Explanation
Lydia ate 4/5 of a pizza and Mark ate 1/10 of a pizza. To find out how much pizza they ate all together, we need to add their individual portions. When we add 4/5 and 1/10, we get a common denominator of 10. So, 4/5 can be written as 8/10. Adding 8/10 and 1/10 gives us 9/10. Therefore, Lydia and Mark ate a total of 9/10 of a pizza all together.

Mrs. Estes baked brownies. She ate 1/12 of the brownies in the pan and gave 7/12 of the brownies in the pan to her neighbor. What fraction of the brownies in the pan were left?
Correct Answer
A. 1/3 pan of brownies
Explanation
After Mrs. Estes ate 1/12 of the brownies and gave 7/12 of the brownies to her neighbor, the total fraction of brownies taken is 1/12 + 7/12 = 8/12. To find the fraction of brownies left, we subtract this fraction from 1 (whole pan). 1 - 8/12 = 4/12. Simplifying this fraction, we get 1/3. Therefore, 1/3 pan of brownies were left.
