Jerome has 20 classmates on his cell phone contact list. He has half as many out of school friends as classmates on his contact list. He also has his two parents and his sister on his contact list. How many people are on Jerome's contact list?
Let's think: Jerome has 20 classmates on the list, and has half as many out of school friends on there so he has 20 / 2 = 10 out of school friends on the contact list. He has 2 parents and 1 sister on the contact list, for 2 + 1 = 3 family members on the contact list. Adding the classmates, out of school friends and family members together we get 20 + 10 + 3 = 33 people on his contact list.. The answer is: 33.

Haruto has tomato plants in his backyard. This year the plants grew 127 tomatoes. Birds had eaten 19 of the tomatoes. He picked the rest. If Haruto gave half of his tomatoes to his friend, how many tomatoes does he have left?
Let's think: After the birds ate 19 of the tomatoes Haruto has 127 - 19 = 108 tomatoes left. After giving half of his tomatoes to his friend, Haruto had 108 / 2 = 54 tomatoes.. The answer is: 54.

A singer is planning on releasing 3 songs in a month. If he worked on one song for 10 hours a day, and each song took 10 days to be completed, calculate the total number of hours he took to complete the 3 songs.
Let's think: If he worked on a song for 10 hours a day, the total number of hours he takes to complete one song is 10 * 10 = 100 hours. If one song took 100 hours to complete, the total number of hours the three songs took to be completed is 3 * 100 = 300 hours.. The answer is: 300.

Simeon drinks 64 fluid ounces of filtered water every day. He used to drink this water in 8-ounce-servings. But now, he drinks his water in 16-ounce servings. How many fewer servings per day does it now take Simeon to drink his water than it used to?
Let's think:
In 64 fluid ounces, there are 64 / 8 = 8 eight - ounce servings. Using 16 - ounce servings, Simeon now drinks 64 ounces in 64 / 16 = 4 servings. Thus, Simeon now drinks his water in 8 - 4 = 4 fewer servings per day.. The answer is: 4.
