A faucet drips 2/5 gallon of water in 3 1/2 hours. What is the unit rate of water dripped per hour?
den301095 [7]

Answer: Unit rate = 4/35 of a gallon per hour

=============================================

Work Shown:

3 & 1/2 = 3 + 1/2

3 & 1/2 = 6/2 + 1/2

3 & 1/2 = (6+1)/2

3 & 1/2 = 7/2

The faucet drips 2/5 of a gallon in 7/2 hours

2/5 gallon : 7/2 hours

2*(2/5 gallon) : 2*(7/2 hours) ..... multiply both sides by 2

4/5 gallon : 7 hours

(1/7)*(4/5 gallon) : (1/7)*(7 hours) ... multiply both sides by 1/7

4/35 gallon : 1 hour

The unit rate is 4/35 of a gallon per hour.

"Per hour" means "every 1 hour".

Ms. Erin had 25 students in on of her math classes last semester. Now this class has 22 students. What is the percent of change?
-Dominant- [34]

Answer:

12% decrease

Step-by-step explanation:

[(new value - old value) / old value] x 100

(22 - 25) / 25 = -3/25 = -0.12

-0.12 x 100 = -12%

when you have a negative it indicates a decrease rather than an increase
