There are 28 students in a class. Two-sevenths of them were absent last Monday. How many students were present last Monday?
Let's think: 28 x 2 / 7 = 8 students were absent last Monday. So, 28 - 8 = 20 students were present last Monday.. The answer is: 20.

The temperature in New York in June 2020 was 80 degrees. If the temperature in Miami on this day was 10 degrees hotter than the temperature in New York, and 25 degrees cooler than the temperature in San Diego, what was the average temperature for the three cities?
Let's think: If it was 10 degrees hotter on this day in Miami than in New York, then the temperature in Miami was 80 + 10 = 90 degrees. If it was 25 degrees cooler in Miami than in San Diego, then the temperature in San Diego was 90 + 25 = 115 degrees. The total temperature for all the cities is 115 + 90 + 80 = 285 degrees. The average temperature of the three cities is 285 / 3 = 95 degrees.. The answer is: 95.

The bakery made 95 muffins. They will be packed in boxes with 5 muffins in each box. If there are only 10 available boxes, how many boxes do they still need to pack all the muffins?
Let's think: A total of 10 x 5 = 50 muffins will be packed in 10 boxes. So 95 - 50 = 45 muffins still need to be packed in the boxes. Thus, 45 / 5 = 9 boxes are still needed to pack all those 45 muffins.. The answer is: 9.

Paige bought some new stickers and wanted to share them with 3 of her friends. She decided to share a sheet of 100 space stickers and a sheet of 50 cat stickers equally among her 3 friends. How many stickers will she have left?
Let's think:
Paige has 100 space stickers that she is dividing among 3 friends, so 100 stickers / 3 friends = 33 stickers for each friend, with 1 remaining. She also has 50 cat stickers that she is diving among 3 friends, so 50 stickers / 3 friends = 16 stickers for each friend, with 2 remaining. So Paige will have 1 remaining space sticker + 2 remaining cat stickers = 3 stickers left.. The answer is: 3.
