Q: Bingley has 5 bracelets. Kelly gives Bingley a fourth of her 16 bracelets. Then Bingley gives a third of his bracelets to his little sister. How many bracelets does Bingley have remaining?
A: Kelly gives Bingley 16 / 4 = 4 bracelets. Bingley has 5 + 4 = 9 bracelets. Bingley gives his little sister 9 / 3 = 3 bracelets. In the end, Bingley has 9 - 3 = 6 bracelets remaining. The answer is 6.
Question: Madeline has 5 boxes with 24 crayons in each. She noticed that 5/8 of the crayons in the 2 boxes were not yet used. In the 2 other boxes, only 2/3 of the crayons were used while the last box was not entirely used. How many unused crayons did Madeline have?
Answer: Two boxes of crayons have 24 x 5 / 8 = 15 unused crayons from each box. So, a total of 15 x 2 = 30 unused crayons are in the two boxes. For the other 2 boxes, there are 24 x 2 / 3 = 16 used crayons from each box. Hence, there are 24 - 16 = 8 unused crayons. So, a total of 8 x 2 = 16 unused crayons are in the other two boxes. Therefore, Madeline has a total of 30 + 16 + 24 = 70 unused crayons. The answer is 70.
[Question]Anne is 2 times as tall as her sister while Bella is 3 times as tall as Anne. If Anne is 80cm tall, what is the height difference between Bella and Anne's sister?
[Answer]Anne is 2 times as tall as her sister hence 2 * (her sister's height) = 80cm. Her sister's height = 80cm / 2 = 40cm. Bella is 3 times as tall as Anne hence Bella's height is 3 * 80 cm = 240 cm. The height difference between Bella and Anne's sister = 240 - 40 = 200cm. The answer is 200.
Q: A club with 30 members ordered fruit juices. Two-fifths of them ordered lemon juice. One-third of the remaining members ordered mango juice, and the rest ordered orange juice. How many members ordered orange juice?
A: 30 x 2 / 5 = 12 members ordered lemon juice. So, 30 - 12 = 18 members did not order lemon juice. Since 1 / 3 of the remaining ordered mango juice, then 18 x 2 / 3 = 12 members ordered mango juice. Therefore, 18 - 12 = 6 members ordered orange juice. The answer is 6.

Twice the length of Christopher's sword is 15 x 2 = 30 inches. So, Jameson's sword is 30 + 3 = 33 inches long. June's sword is 33 + 5 = 38 inches long. Thus, June's sword is 38 - 15 = 23 inches longer than Christopher's sword. The answer is 23.
