I did try but I couldn't figure it out so I need help!!!!

Is it right?

To answer the given questions, we will go through each question step by step:

1. The ratio of the number of school signs to the number of stop signs can be found by dividing the number of school signs by the number of stop signs. In this case, you haven't provided the actual numbers, so the correct answer cannot be determined.

2. To find the equivalent ratio to four over sixteen, you can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which in this case is 4. Simplifying the fraction gives 1 over 4, which can be written as the ratio 1:4.

3. To write the ratio of 8 meters in 10 seconds as a unit rate, you divide the number of meters by the number of seconds. So, 8 meters divided by 10 seconds is equal to 0.8 meter per second.

4. To write the ratio of 27 miles in one-half hour as a unit rate, you divide the number of miles by the number of hours. However, in this case, the time given is in one-half hour, so we need to convert it to hours. One-half hour is equivalent to 0.5 hours. So, 27 miles divided by 0.5 hours is equal to 54 miles per hour.

5. To determine who has the fastest reading rate, we need to calculate the rate at which each person reads. Rate is measured as pages read per minute.

a) Carla reads 45 pages in 90 minutes. By dividing the number of pages by the number of minutes, we find that Carla's reading rate is 0.5 pages per minute.
b) Josh reads 28 pages in 56 minutes. Dividing, we find that Josh's reading rate is 0.5 pages per minute.
c) Malik reads 67 pages in 134 minutes. Dividing, we find that Malik's reading rate is also 0.5 pages per minute.

Therefore, all three individuals read at the same rate.

6. The ratio of the time Pam spends driving home from work to the time she spends driving to work can be written as:
- 60 minutes:45 minutes
- 4:3
- 4/3

7. a) To find the unit price (price per ounce) of the lemonade mix at the grocery store, divide the total price ($2.00) by the number of ounces (25). The unit price is $0.08 per ounce.

b) To find the unit price of the lemonade mix at the wholesale club, divide the total price ($6.75) by the number of ounces (75). The unit price is $0.09 per ounce.

c) You should buy the lemonade mix at the grocery store because the unit price is lower ($0.08 per ounce) compared to the wholesale club ($0.09 per ounce).

8. To convert the map scale to a unit rate, you need the given relationship between inches and miles. If the map scale states that 1 inch represents 10 miles, then the unit rate is found by dividing the number of inches by the number of miles. So, 1 inch divided by 10 miles is equal to 1/10 inches per mile. The unit rate means that for every mile, 1/10 of an inch on the map represents it in reality.
