Consider the Q and A. Q: Donna is catering for a party. She makes 20 sandwiches and then cuts them in half, before cutting them in half again. She then gives everyone 8 portions. How many people can she feed?
A: 10
What is the step-by-step reasoning process?
Step-by-step reasoning process: First, we need to determine the overall number of portions. To do this, we begin by performing 20 * 2 = 40 portions after the first halving. Next, we take this portion number and double it again, performing 40 * 2 = 80 portions after the second halving. Lastly, we divide this portion number by the number of portions each person will be served, performing 80 / 8 = 10 people served.

Consider the Q and A. Q: Tenisha had 40 dogs that she kept at home as pets. If 60% of them are female, and 3/4 of the female gives birth to 10 puppies each, calculate the total number of puppies that Tenisha remains with after donating 130 puppies to the church.
A: 50
What is the step-by-step reasoning process?
Step-by-step reasoning process: If Tenisha has 40 dogs, the number of female dogs is 60 / 100 * 40 = 24. 3 / 4 of the females give birth, meaning 3 / 4 * 24 = 18 female dogs gives birth to puppies. Since each dog that gave birth had 10 puppies, the number of puppies that were born is 18 * 10 = 180. After donating 130 puppies to the church, Tenisha remained with 180 - 130 = 50 puppies.

Consider the Q and A. Q: Jeff’s swimming coach required him to swim 98 laps over the weekend. On Saturday, Jeff swam 27 laps. On Sunday morning, he swam 15 laps, took a break, then resumed practice in the afternoon. How many laps did Jeff have remaining when he took the break?
A: 56
What is the step-by-step reasoning process?
Step-by-step reasoning process: After Jeff swam on Saturday, there remained 98 - 27 = 71 laps. After Sunday morning’s 15 laps there remained 71 - 15 = 56 laps. Therefore, when Jeff took the break, he had 56 laps remaining.

Consider the Q and A. Q: Mark wants to set the record for most consecutive ropes jumped. The record is 54,000. He can jump 3 times a second. How many hours would he need to jump rope?
A: 5
What is the step-by-step reasoning process?
Step-by-step reasoning process:
He can jump 3 * 60 = 180 times per minute. So he can jump 180 * 60 = 10,800 per hour. So it would take him 54,000 / 10,800 = 5 hours.
