Question: The ratio of fuel used in gallons to the distance covered in miles by Haley's car is 4:7. If Haley's car used 44 gallons of gas, calculate the distance it covered in miles.
Answer: Step-by-step reasoning process: The total ratio representing fuel consumption and distance traveled is 4 + 7 = 11. If 4 / 11, which is the fraction representing fuel consumption, represents 22 gallons of gas, then 7 / 11 representing distance covered represents 7 / 11 * 44 * 11 / 4 = 77 miles.
So the answer is 77.

Question: Louis has 5 oranges and 3 apples. Samantha has 8 oranges and 7 apples. If Marley has twice as many oranges as Louis and three times as many apples as Samantha, how many fruits in total does Marley have?
Answer: Step-by-step reasoning process: Marley has twice as many oranges as Louis (who has 5 oranges) for a total of 2 * 5 = 10 oranges. He also has thrice as many apples as Samantha (who has 7 apples) for a total of 3 * 7 = 21 apples. Marley has a total of 10 + 21 = 31 fruits.
So the answer is 31.

Question: Carter has a jar with 20 green M&Ms and 20 red M&Ms. He eats 12 of the green M&Ms, then his sister comes and eats half the red M&Ms and adds 14 yellow M&Ms. If Carter picks an M&M at random now, what is the percentage chance he'll get a green M&M?
Answer: Step-by-step reasoning process: First find the final number of green M&Ms by subtracting 12 from the starting number: 20 M&Ms - 12 M&Ms = 8 green M&Ms. Then find the final number of red M&Ms by dividing the starting number by half: 20 M&Ms / 2 = 10 red M&Ms. Then find the total number of M&Ms at the end by adding the number of red, green and yellow M&Ms: 8 M&Ms + 10 M&Ms + 14 M&Ms = 32 M&Ms. Then divide the number of green M&Ms by the total number of M&Ms and multiply by 100 to find the percentage chance Carter gets a green M&M: 8 M&Ms / 32 M&Ms * 100 = 25%.
So the answer is 25.

Question: Jolene and Phil have four children, each with the same birthday. They gave birth to their first child exactly 15 years ago. They gave birth to their second child exactly one year after the birth of their first child. They gave birth to their third child on the fourth birthday of their second child. Two years after the birth of their third child, they gave birth to their fourth child. How old, in years, is their fourth child?
Answer:
Step-by-step reasoning process: Their 1st child was born 15 years ago, and therefore is 15 years old. Their 2nd child was born 1 year after their 15 - year - old child, and therefore is 15 - 1 = 14 years old. Their 3rd child was born 4 years after their 14 - year - old child, and therefore is 14 - 4 = 10 years old. Their 4th child was born 2 years after their 10 - year - old child, and therefore is 10 - 2 = 8 years old.
So the answer is 8.
