Carrington used 3/4 of the 1/2 of an hour allotted for an exam to do the first 3 problems. How much time does he have left for tKiley had a piece of bamboo skewer that measured 14 3/5 inches long. She wanted to cut it into toothpicks that were each 3 1/5 inches long. How many toothpicks can she make?He remaining part of the exam?

a. 7.5 minutes

b. 4 and one-half toothpicks

Step-by-step explanation:

a. an hour = 60 minutes

Allotted time for the exam = 1/2 hour = 1/2 * 60 = 30 minutes

He used 3/4 of this time, so the time left in fraction would be 1-3/4 = 1/4

So the time left in minutes is 1/4 * 30 = 7.5 minutes

b. The total length he has here is 14 3/5 inches

Now he wants to cut toothpicks of 3 1/5

To know the number of toothpicks he can cut, we simply divide the total length by the length of each toothpick

14 3/5 divided by 3 1/5

= 73/5 divided by 16/5

= 73/5 * 5/16 = 73/16 = 4.5625

which is closer to 4 and one-half toothpicks
