Question: 240 sixth-grade students were asked about the number of novels they read per month. 1/6 of students read three or more novels, 35% of students read two novels, 5/12 of students read one novel, and the rest of the students do not read anything. Calculate the number of students who do not read novels.
Answer with step-by-step thinking: 1 / 6 * 240 students = 40 students. So 40 students read three or more novels. 35 / 100 * 240 students = 84 students. So 84 students read two novels. 5 / 12 * 240 students = 100 students. So 100 students read a novel. 240 students – (40 students + 84 students + 100 students) = 240 students – 224 students = 16 students. So 16 students don't read novels.
So the answer is 16.


Question: Madeline spends 18 hours a week in class. She spends 4 hours per day working on homework. She spends 8 hours per day sleeping. She works part-time 20 hours per week. How many hours left over does Madeline have?
Answer with step-by-step thinking: Madeline spends 4 * 7 = 28 hours on homework. She spends 8 * 7 - 56 hours sleeping. Therefore, she is busy 28 + 18 + 56 + 20 = 122 hours per week. There are 7 * 24 = 168 hours per week. Thus, Madeline has 168 - 122 = 46 hours left over.
So the answer is 46.


Question: Carrie is making punch. She adds 6 12-oz cans of Mountain Dew, 28 oz of ice, and a 40 oz bottle of fruit juice. How many 10 oz servings of punch does Carrie have?
Answer with step-by-step thinking:
First find the total volume of the Mountain Dew: 6 cans * 12 oz / can = 72 oz. Then find the total volume of the punch: 72 oz + 28 oz + 40 oz = 140 oz. Then divide the total volume by the volume of each serving to find the number of servings: 140 oz / 10 oz / serving = 14 servings.
So the answer is 14.
