Fraction Division Answers 2E3Ef8

1. Howard read 1/6 of a book each day until he finished two books. How many days did it take Howard to read both books? 2. The school day is 7 hours long. If recess lasts 1/4 hour, what fraction of the school day does recess make up? 3. Janet has 8 ounces of coffee beans. If each cup of coffee requires 1/9 ounce of coffee beans, how many cups of coffee can Janet make? --- 1. To find the number of days Howard read, divide the total books by the fraction read each day: $$\text{Days} = \frac{2}{\frac{1}{6}} = 2 \times 6 = 12$$ Howard read his books for 12 days. 2. To find the fraction of the school day that recess makes up, divide recess time by total school day time: $$\text{Fraction} = \frac{\frac{1}{4}}{7} = \frac{1}{4} \times \frac{1}{7} = \frac{1}{28}$$ Recess is $\frac{1}{28}$ of a school day. 3. To find how many cups of coffee Janet can make, divide total ounces by ounces per cup: $$\text{Cups} = \frac{8}{\frac{1}{9}} = 8 \times 9 = 72$$ Janet can make 72 cups of coffee.
