Step-by-step reasoning process: Bexley gives Hershel 2 / 5 * 10 = 4 betta fish. The total number of betta fish in the bowl is now 4 + 10 = 14. He also gives Hershel 1 / 3 * 15 = 5 goldfish. The total number of goldfish in the bowl is now 15 + 5 = 20. Counting the betta fish and goldfish, Hershel now has a total of 14 + 20 = 34 fish. When he gives his sister half of the fish, the remaining half is 34 / 2 = 17 fish.
The question and answer:
Question and answer: Hershel has 10 betta fish and 15 goldfish in a bowl. His friend Bexley brings him 2/5 times as many betta fish and 1/3 times as many goldfish. If Hershel gifts his sister 1/2 of the fish, calculate the total number of fish he has remaining in the bowl.
The answer is 17

Step-by-step reasoning process: Tina has already cleaned one key so she has 14 left which take 3 minutes each to clean, 14 x 3 = 42 minutes to clean all the keyboard keys. Her assignment will take 10 minutes to complete, so she needs 42 minutes + 10 minutes = 52 minutes total before dinner.
The question and answer:
Question and answer:
Tina is working on her homework when she realizes she's having a hard time typing out her answers on her laptop because a lot of the keys are sticky. She is trying to get her homework done before dinner, though, so she needs to decide if she has time to clean her keyboard first. Tina knows her assignment will only take 10 minutes to complete. Dinner will be ready at 5:30 p.m. Tina decides to time how long it takes to remove and clean one key and will then multiply that time by how many keys she needs to fix. She counts 15 keys that are sticky and times it to take 3 minutes to clean one. After Tina has cleaned one key, there are 14 left to clean. How many minutes total will it take for Tina to both clean the remaining keys and finish her assignment?
The answer is 52
