Reasoning and answer: We calculate 50% of 16 GB:. 50 / 100 * 16 GB = 0.5 * 16 GB = 8 GB. That leaves 16 GB - 8 GB = 8 GB available on this key.
The answer: 8

Question: On a 16 GB (gigabyte) capacity USB drive, 50% is already busy. Calculate the number of gigabytes still available.
Altogether, Georgie has 5 + 4 = 9 avocados. She can make 9 / 3 = 3 servings of guacamole.
The answer: 3
Reverse engineering the question: Georgie needs 3 avocados to make her grandmother's guacamole recipe. If she already had 5 avocados and her sister buys another 4 avocados, how many servings of guacamole can Georgie make?
Reasoning and answer: In her hamper, Brie has 12 x 75% = 9 blouses. In her hamper, she has 6 x 50% = 3 skirts. In the hamper, she has 8 x 25% = 2 slacks. She will need to wash 9 + 3 + 2 = 14 pieces of clothes.
The answer: 14
What was the question?
Question: When all her clothes are washed and in her closet, Brie has 12 blouses, 6 skirts, and 8 slacks. Today in her hamper, she has 75% of her blouses, 50% of her skirts, and 25% of her slacks. How many pieces of clothing will she need to put in the washer?
If Sophie has twice as many dolls as Vera, then she has 2 * 20 dolls = 40 dolls. Aida has 2 * 40 dolls = 80 dolls, twice the number Sophie has. In total, they have 80 dolls + 40 dolls + 20 dolls = 140 dolls.
The answer: 140
Reverse engineering the question: Aida has twice as many dolls as Sophie, and Sophie has twice as many dolls as Vera. How many dolls do Aida, Sophie, and Vera have combined if Vera has 20 dolls?
Reasoning and answer: Stella and Twinkle filled up the truck at the rate of 250 blocks per hour per person, a total of 2 * 250 = 500 blocks per hour for both. After working for four hours, Stella and Twinkle had filled 4 * 500 = 2000 blocks into the truck. The number of blocks they had to put into the truck for it to be full is 6000 - 2000 = 4000. When 6 more people joined Stella and Twinkle, a total of 2 + 6 = 8 people were filling the truck now. Working at the rate of 250 blocks per person, the eight people filled the truck with 250 * 8 = 2000 blocks in one hour. If there were 4000 blocks that still needed to be put into the truck, the 8 people took 4000 / 2000 = 2 hours to fill the truck with the blocks. The total time it took to fill up the tank is 4 + 2 = 6 hours.
The answer: 6

Question: Stella and Twinkle are filling up a truck with a capacity of 6000 stone blocks at the rate of 250 blocks per hour per person. They work for four hours and are then joined by 6 other people who also work at the same rate. How many hours did filling the truck take?
Reasoning and answer: Today, Sheila's piggy bank has $3000 + $7000 = $10000. Sheila will be saving for 4 years which is equivalent to 12 months / year * 4 years = 48 months. In 4 years, she will save $276 / month * 48 months = $13248. The piggy bank will have a total of $10,000 + $13,248 = $23248.
The answer: 23248
