Emily can type 60 words per minute. How many hours does it take her to write 10,800 words? Give the rationale and then the answer.
Let's think step by step. In an hour, Emily can type 60 words * 60 minutes = 3600 words. It will take her 10800 / 3600 = 3 hours to write 10800 words.. The answer is: 3.

Together 3 friends watched 411 short videos. Kelsey watched 43 more than Ekon. Ekon watched 17 less than Uma. How many videos did Kelsey watch? Give the rationale and then the answer.
Let's think step by step. Let U = the number of videos Uma watched. Ekon = U - 17. Kelsey = (U - 17) + 43 = U + 26. U + U - 17 + U + 26 = 411. 3U + 9 = 411. 3U = 402. U = 134. Kelsey = 134 + 26 = 160 videos. Kelsey watched 160 videos.. The answer is: 160.

Ben has two brothers. They can each eat 12 slices of pizza. They are ordering pizza for the night and want to make sure they get enough. The large pizzas have 14 slices and the small pizzas have 8. If they order 1 small pizza, how many large pizzas do they need to order? Give the rationale and then the answer.
Let's think step by step. They need 36 slices because 3 x 12 = 36. After ordering the small, they need 28 slices because 36 - 8 = 28. They need 2 large pizzas because 28 / 14 = 2.. The answer is: 2.
