Question: Bailey is making a rectangle out of a 100cm length of rope he has. If the longer sides of the rectangle were 28cm long, what is the length of each of the shorter sides?
Answer: The longer sides are 2 in number so their total length of 2 * 28cm = 56cm. The rest of the length making up the short sides is 100 - 56 = 44 cm. There are two equal short sides so each one is 44 / 2 = 22cm. The answer is 22.
[Question]Kwame studied for the history test for 2.5 hours. Connor studied for 1.5 hours and Lexia studied for 97 minutes. How many minutes more did Kwame and Connor study than Lexia?
[Answer]Kwame = 2.5 hours * 60 minutes = 150 minutes. Connor = 1.5 hours * 60 minutes = 90 minutes. Kwame + Connor = 150 + 90 = 240 minutes. 240 - 97 = 143 minutes. Kwame and Conner studied 143 minutes more than Lexia. The answer is 143.
Q: Thomas owns 200 books. He decides to sell them and use the money to buy records. Each book sells for $1.5. A record costs $3. If he buys 75 records, how much money does he have left over?
A: He makes $300 selling the books because 200 x 1.5 = 300. He spends $225 on records because 75 x 3 = 225. He has $75 left because 300 - 225 = 75. The answer is 75.
Question: Tyler has $100. If he buys 8 scissors for $5 each and 10 erasers for $4 each, how much of his money remains?
Answer: 8 * $5 = $40 is the price of 8 scissors. 10 * $4 = $40 is the price of 10 erasers. You can find the total price by adding the cost of the scissors and erasers: $40 + $40 = $80. $100 - $80 = $20 is the remaining amount of his money. The answer is 20.
[Question]Don can paint 3 tiles a minute, Ken can paint 2 more tiles a minute than Don and Laura can paint twice as many tiles as Ken. Kim can paint 3 fewer tiles than Laura can in a minute. How many tiles can Don, Ken, Laura and Kim paint in 15 minutes?
[Answer]Ken paints 3 tiles / minute + 2 tiles / minute = 5 tiles / minute. Laura can paint 5 tiles / minute x 2 = 10 tiles / minute. Kim can paint 10 tiles / minute - 3 tiles / minute = 7 tiles / minute. All 4 can paint 3 tiles / minute + 5 tiles / minute + 10 tiles / minute + 7 tiles / minute = 25 tiles / minute. In 15 minutes, they can paint 15 minutes x 25 tiles / minute = 375 tiles. The answer is 375.
[Question]There are 92 students altogether. Twenty of them ride the school bus home together, 5/8 of the remaining ride their own bike home, and the rest whose houses are near the school walk home. How many students are walking home?
[Answer]
If there are 92 students and 20 students take the bus home, the number of students who haven't taken the bus is 92 - 20 = 72 students. 5 / 8 of the students who didn't take the bus home ride bikes home, a total of 5 / 8 * 72 = 45 students. The number of students who neither took the bus nor biked home but walked home is 72 - 45 = 27. The answer is 27.
