Question: There are 45 children in a classroom. One-third of them are girls. How many boys are in the classroom?

[Question]Anna is making gingerbread cookies. She gives 6 of them red hats, 9 of them blue boots, and 3 of them both red hats and blue boots. What percentage of the gingerbread men have red hats?
[Answer]The first step to find the total number of gingerbread men is to add the number with each decoration: 6 men + 9 men = 15 men. Then subtract the number of gingerbread men with both decorations to find the total number of gingerbread men: 15 men - 3 men = 12 men. Then divide the number of gingerbread men with red hats by the total number and multiply by 100% to express the answer as a percentage: 6 men / 12 men * 100% = 50%. The answer is 50.
Q: Daniel collects Russian dolls that normally cost $4 each. He saves enough money to buy 15 Russian dolls. However, the price suddenly drops to $3 each. How many Russian dolls can he buy now at the discounted price, given his savings?
A: With the price of each doll at $4, this means he has saved a total of 15 * 4 = $60. When the price is lowered to $3 each, he can now purchase 60 / 3 = 20 dolls. The answer is 20.
Question: The Zargon Destroyer spacecraft can travel at 2 billion miles per hour in normal space, but when moving through a black hole they travel three times faster. If the Zargon Destroyer is making a voyage that travels seven hours in normal space and two hours through a black hole, how many billions of miles would they have traveled?
Answer: A spacecraft flying through normal space for seven hours at 2 - billion miles per hour travels 7 * 2 = 14 billion miles. A spacecraft flying through a black hole at 3 * 2 = 6 billion miles per hour. Thus, a spacecraft flying through a black hole for two hours travels 2 * 6 = 12 billion miles. Therefore, in total, the Zargon spacecraft will travel 14 + 12 = 26 billion miles. The answer is 26.
[Question]300 cows in a field are made up of male and female cows. There are twice as many females as males. Half the females are spotted, and half the males have horns. How many more females with spots are there than males with horns?
[Answer]There are (300 / 3) x 2 = 100 x 2 = 200 females cows in the field. There are 200 / 2 = 100 male cows in the field. 200 / 2 = 100 female cows are spotted. 100 / 2 = 50 male cows have horns. There are 100 - 50 = 50 more females with spots than males with horns. The answer is 50.
[Question]A pumpkin patch allows people to come pick pumpkins to carve in the fall every year. They charge $3 per person for a pumpkin. The remaining pumpkins get turned into cans of pie filling, 3 pumpkins to a can. They grew 83 pumpkins this year and made $96 selling pumpkins for carving. How many cans of pie filling will the pumpkin patch produce?
[Answer]
The pumpkin patch sold 96 / 3 = 32 pumpkins. They have 83 - 32 = 51 pumpkins left. Thus, the pumpkin patch will produce 51 / 3 = 17 cans of pie filling. The answer is 17.
