Answer:

1) 7:10

2) $8 per hour

Step-by-step explanation:

Question 1

What we know:

- there are 10 seventh grade students

- there are 7 sixth grade students

Therefore, the ratio of sixth-grade students to seventh-grade students is 7:10.

Question 2

What we know:

- Janice babysat 3 hours each night

- Janice babysat for 8 nights

- she earned $192

First, we need to find the total number of hours that she babysat. Because she babysat for 3 hours each night for 8 nights, we can find this by multiplying 3 and 8:

3×8=24

Therefore, Janice babysat for 24 hours in total.

Because she earned a total of $192, divide 192 by 24 to find her hourly rate:

192÷24=8

Therefore, Janice has an hourly rate of $8 per hour.

I hope this helps!
