Question 1: To find the quotient of 9/10 and 2/3, we divide 9/10 by 2/3. This can be done by multiplying the numerator of the first fraction (9) by the reciprocal of the second fraction (3/2). So, the answer is (9/10) * (3/2) = 27/ 20. The correct answer is C. 27/20.
Question 2: To divide 3/10 by 1/3, we again multiply the first fraction by the reciprocal of the second fraction. So, the answer is (3/10) * (3/1) = 9/10. The correct answer is B. 9/10.
Question 3: If Stacy can paint 3/4 of the bedroom in 3 hours, then we can set up a proportion to find out how long it will take her to paint the entire room. The proportion is (3/4) / 3 = 1 / x. Solving for x, we get x = 12. So, it will take Stacy 12 hours to paint the entire room. The correct answer is C. 12 hours.
Question 4: If Miguel has driven 2/3 of the total distance in 4 hours, we can set up a proportion to find out how long the total drive will take. The proportion is (2/3) / 4 = 1 / x. Solving for x, we get x = 6. So, it will take Miguel a total of 6 hours to reach his destination. The correct answer is B. 6 hours.
Question 5: If Iris can complete 2/3 of the floor in 1/3 of an hour, we can set up a proportion to find out how long it will take her to complete the entire floor. The proportion is (2/3) / (1/3) = 1 / x. Solving for x, we get x = 1. So, it will take Iris 1 hour to complete the entire floor. The correct answer is A. 1 hour.
