Questions 1, 2, and 3
Answer:
1. C) 5/2
2. 0.3125
3. The average change in the height of rainwater is approximately -1.25 inches per day.
Explanation:
1. -5/6 divided by -1/3
Keep, change, flip
Keep the first term, change the division into multiplication, and flip the last term so that it is -3/1
-5/6 times -3/1
Simplify by crossing out the 3 and the 6. The 3 becomes a 1 and the 6 becomes a 2.
-5/2 times -1/1
The answer is 5/2.
2. 5 divided by 16 is 0.3125
3. Average Change = Final Height - Initial Height / Time
Average Change = 18.08 in. - 24.83 in. / 5 and 5/2 days
Subtract the heights.
Average Change = -6.75 in. / 5 and 5/2 days
Convert the mixed number to an improper fraction.
Average Change = -6.75 in. / 27/5 days
Multiply by the reciprocal of the denominator:
Average Change = -6.75 in. times 5/27 days
Perform the multiplication:
Average Change = approximately -1.25 in. per day.
The average change in the height of rainwater is approximately -1.25 inches per day.
