Answer the following question.
Jane had a 500 page book to read. The first half of the book Jane read with a speed of 10 pages per day, and the second half with a speed of 5 pages a day. How many days did Jane spend reading this book?
Step-by-step reasoning process: Half of the book means 500 / 2 = 250 pages. Reading the first half took Jane 250 / 10 = 25 days. Reading the second half of the book took Jane 250 / 5 = 50 days. So in total Jane needed 25 + 50 = 75 days to read the whole book.
The answer is 75.

Answer the following question.
Bob wants to build a pyramid out of legos with 3 levels where the bottom level has 7 legos per side and each level has one less lego per side than the level below it. How many legos total will he need?
Step-by-step reasoning process: First find the total number of legos on the bottom layer: 7 legos * 7 legos = 49 legos. Then find the number of legos per side on the next layer: 7 legos - 1 lego = 6 legos. Then find the total number of legos on the second level: 6 legos * 6 legos = 36 legos. Then find the number of legos per side on the top level: 6 legos - 1 lego = 5 legos. Then find the total number of legos on the top level: 5 legos * 5 legos = 25 legos. Then add the number of legos on each level to find the total number of legos: 49 legos + 36 legos + 25 legos = 110 legos.
The answer is 110.

Answer the following question.
Matthew and his brother Shawn played swimming-pool-basketball. Each basket was worth 3 points. Matthew scored 9 points. Shawn scored 6 points. What is the total number of baskets made during this game?
Step-by-step reasoning process: Matthew scored 9 points and there are 3 points per basket, so he made 9 / 3 = 3 baskets. Shawn scored 6 points, so he made 6 / 3 = 2 baskets. The total number of baskets made is 3 + 2 = 5 baskets made.
The answer is 5.

Answer the following question.
Andy is mixing blue, green and white paint in a 1 : 2 : 5 ratio. If he uses 6 gallons of green paint, how many gallons of paint does he use total?
Step-by-step reasoning process: First find the number of gallons of blue paint by multiplying the gallons of green paint by the ratio between the blue and green paint: 1 blue gallon / 2 green gallons * 6 gallons = 3 gallons. Then find the number of gallons of white paint by multiplying the gallons of green paint by the ratio between the white and green paint: 5 white gallons / 2 green gallons * 6 gallons = 15 gallons. Then add the number of gallons of each color to find the total number of gallons of paint: 6 gallons + 3 gallons + 15 gallons = 24 gallons.
The answer is 24.
