Bella needs a total of 8 beads x 6 friends = 48 beads. She needs 48 beads 36 beads = 12 more beads.
The answer: 12
Reverse engineering the question: Bella is making bracelets for her 6 friends. She needs 8 beads per bracelet. She has 36 beads. How many more beads does she need to make all six bracelets?
Reasoning and answer: The total ratio for the number of cats and dogs that Heloise has is 10 + 17 = 27. From the ratios, the fraction representing the number of dogs is 10 / 27, and this represents 10 / 27 * 189 = 70 dogs. If Heloise gives 10 of her dogs to Janet, she remains with 70 - 10 = 60 dogs.
The answer: 60

Question: Heloise has dogs and cats in the ratio of 10:17, with the total number of pets being 189. If she gives 10 dogs to her friend Janet, how many dogs does she remain with altogether?
There are 30 + 15 + 40 = 85 minutes accounted for. She spent 2 * 60 = 120 minutes. She spent 120 - 85 = 35 minutes cleaning her room.
The answer: 35
Reverse engineering the question: Miriam spent 30 minutes doing laundry, 15 minutes cleaning the bathroom, a certain amount of time cleaning her room, and 40 minutes doing homework. If she spent a total of two hours on these tasks, how long, in minutes, did she spend cleaning her room?
Reasoning and answer: At the end of the day, he had tested 120 boards, each with three tacks, for a total of 3 * 120 = 360 tacks. He had 30 tacks remaining in each of the three cans, for an additional 3 * 30 = 90 thumbs tacks. Therefore, the original total combined number of thumbtacks in the three full cans of thumbtacks was 360 + 90 = 450 thumbtacks.
The answer: 450

Question: Lorenzo put three full cans of thumbtacks into his pocket and went off to work at the corkboard factory. It was Lorenzo's job, as head of quality control, to test every cork board for its ability to hold thumbtacks. He placed one thumbtack from each of the three cans of thumbtacks into every board tested. At the end of the day, he had tested 120 boards and had 30 tacks remaining in each of the three cans. What was the total combined number of thumbtacks from the three full cans?
The dolls will sell for 3 * $5 = $15. The clocks will bring in 2 * $15 = $30. The glasses will sell for 5 * $4 = $20. In total, she will bring in $15 + $30 + $20 = $65. Her total profit will be $65 - $40 = $25.
The answer: 25
Reverse engineering the question: Stella's antique shop has 3 dolls, 2 clocks and 5 glasses for sale. She sells the dolls for $5 each. The clocks are priced at $15 each. The glasses are priced at $4 each. If she spent $40 to buy everything and she sells all of her merchandise, how much profit will she make?
Carter is twice as tall as 24" dog so he is 2 * 24 = 48". Betty is 12" shorter than Carter so Betty is 48 - 12 = 36" tall. 12" is the same as 1 foot so Betty is 36 / 12 = 3 feet tall.
The answer: 3
Reverse engineering the question:
Carter is twice as tall as his 24" tall dog. Betty is 12" shorter than Carter. How tall is Betty in feet?
