Q: There are 36 seagulls on the roof of the Taco Bell. Kids scare 1/4 of them away by throwing stones, and 1/3 of the remaining birds decide to fly to McDonald's parking lot. How many seagulls are left?
A: First find how many birds get scared away by kids: 36 seagulls / 4 = 9 seagulls. Then subtract that number from the starting total: 36 seagulls - 9 seagulls = 27 seagulls. Then divide that number by 3: 27 seagulls / 3 = 9 seagulls. Then subtract that number from the 27 seagulls to find the final number of seagulls: 27 seagulls - 9 seagulls = 18 seagulls. The answer is 18.
Question: Betty has 20 books, and her sister has 1/4 times more books than Betty. What's the total number of books the two have?
Answer: Betty's sister has 1 / 4 * 20 books = 5 more books. The total number of books Betty's sister has is 20 books + 5 books = 25 books. The total number of books the two have is 25 books + 20 books = 45 books. The answer is 45.

Q: Brenda and nine of her friends want to order a pizza. They decide that each person will eat 2 slices. If each pizza has 4 slices, how many pizzas should they order?
A: All together, Brenda and her friends make a group of 1 + 9 = 10 people. If they each want to eat 2 pizza slices, there should be 10 * 2 = 20 slices. Since a pizza has 4 slices, they will have to order 20 / 4 = 5 pizzas. The answer is 5.
Question: Teresa orders 2 fancy ham and cheese sandwiches for $7.75 each at a local shop. While there, she decides to pick up some salami for $4.00, more brie which is three times the price of the salami, a 1/4 pound of olives that are $10.00 per pound, 1/2 pound of feta cheese that’s $8.00 a pound and another loaf of french bread that is $2.00. How much does she spend at the local shop?
Answer: She orders 2 sandwiches that are $7.75 so they cost 2 * $7.75 = $15.50. The brie is three times more expensive than the $4.00 salami so the brie costs 3 * $4 = $12.00. She buys 1 / 4 pound of the olives that costs $10.00 a pound so they cost .25 * $10 = $2.50. She buys 1 / 2 pound of feta that costs $8.00 a pound so it costs .5 * $8 = $4.00. The salami is $4.00, the brie is $12.00, olives are $2.50 and the feta is $4.00 and the sandwiches are $15.50 for a total of $4 + $12 + $2.50 + $4 + $15.50 = $38.00. Adding the french bread gives $38.00 + $2.00 = $40. The answer is 40.
Q: For Mother's Day last year, Kyle picked a dozen roses from his garden, but this year, he was only able to pick half the number of roses. If Kyle wants to give his mother a bouquet with twice as many roses as last year and the grocery store sells one rose for $3, how much would Kyle have to spend?
A:
This year, Kyle was only able to pick 12 / 2 = 6 roses. He wants to give his mother 12 x 2 = 24 roses. He still needs another 24 - 6 = 18 roses. He would have to spend 18 x 3 = $54. The answer is 54.
