[Question]Bill started reading a book on the first day of April. He read 8 pages every day and by the 12th of April, he had covered two-thirds of the book. How many pages does the book have?
[Answer]He read 8 pages every day for 12 days for a total of 8 * 12 = 96 pages. 96 pages is the same as two - thirds of the total number of pages which means: number of pages * (2 / 3) = 96. Therefore the total number of pages is 96 * (3 / 2) = 144 pages. The answer is 144.
Q: At a laundromat, it costs $4 for a washer and a quarter for every 10 minutes in the dryer. Samantha does 2 loads of laundry in the wash and then divides all the washed clothes equally into 3 separate dryers. If she lets the dryers run for 40 minutes each, how much does she spend altogether?
A: Samantha spends $4 x 2 = $8 on washing. Each dryer costs 25 x 4 = 100 cents = $1. Three dryers cost 1 x 3 = $3. Altogether, she spends 8 + 3 = $11. The answer is 11.
Question: Milena is 7 years old, and her grandmother is 9 times older than her. Milena's grandfather is two years older than her grandmother. What is the age difference between Milena and her grandfather?
Answer: Milena's grandmother is 7 * 9 = 63 years old. Her grandfather is 63 + 2 = 65 years old. So the age difference between Milena and her grandfather is 65 - 7 = 58 years. The answer is 58.
[Question]Matt spends 80 minutes washing the outside of his car and 1/4 that amount of time cleaning the inside. How long does he spend cleaning his car total?
[Answer]First find the time Matt spends cleaning the inside of his car: 80 minutes / 4 = 20 minutes. Then add that time to the time he spends cleaning the outside to find his total cleaning time: 20 minutes + 80 minutes = 100 minutes. The answer is 100.
Q: Samantha, Aira, and Joe received 6 rubber bands each after they divided their bands equally. If Samantha had 5 more bands than Aira and Aira had 1 fewer band than Joe, how many rubber bands did Aira have?
A: Samantha, Aira, and Joe have 6 x 3 = 18 rubber bands altogether. If we let x be the number of bands that Aira had, then Samantha had x + 5. Since Aira had 1 fewer band than Joe, then Joe had x + 1. Since the total number of bands is 18, then the equation is x + (x + 5) + (x + 1) = 18. By simplifying the left side of the equation, we have 3x + 6 = 18. Putting all the constant terms on the right side gives 3x = 12. So the value of x is 12 / 3 = 4. Hence, Aira had 4 rubber bands. The answer is 4.
Question: Janet has 60 less than four times as many siblings as Masud. Carlos has 3/4 times as many siblings as Masud. If Masud has 60 siblings, how many more siblings does Janet have more than Carlos?
Answer:
If Masud has 60 siblings, and Carlos has 3 / 4 times as many siblings as Masud, Carlos has 3 / 4 * 60 = 45 siblings. Four times as many siblings as Masud has is 4 * 60 = 240. Janet has 60 less than four times as many siblings as Masud, a total of 240 - 60 = 180 siblings. The number of siblings Janet have more than Carlos is 180 - 45 = 135. The answer is 135.
