Let's go through each question and check the answers:
1. Write the following ratio in simplest form: 32 minutes: 36 minutes
A. 8:9
B. 8:36
C. 32:9
D. 128:144
To simplify the ratio, we can divide both numbers by their greatest common divisor, which is 4. This gives us 8:9, so the correct answer is A.
Your answer is correct.
2. In a sports equipment locker, there are 81 balls and 45 baseball mitts. Write the ratio of balls to mitts in simplest form.
A. 9:5
B. 10:18
C. 10:5
D. 9:18
To simplify the ratio, we can divide both numbers by their greatest common divisor, which is 9. This gives us 9:5, so the correct answer is A.
Your answer is correct.
3. A price of 10 ounces of crackers is $3.00. What is the unit price? Round your answer to the nearest cent.
A. $0.15 per ounce
B. $0.30 per ounce
C. $0.60 per ounce
D. $0.90 per ounce
To find the unit price, we divide the total price by the number of units. In this case, $3.00 divided by 10 ounces is $0.30 per ounce. So the correct answer is B.
Your answer is correct.
4. Find the unit rate for the situation.
360 km in 6 h.
A. 60 km/h
B. 120 km/h
C. 62 km/h
D. 60 km/h
To find the unit rate, we divide the total quantity by the number of units. In this case, 360 km divided by 6 hours is 60 km/h. So the correct answer is A.
Your answer is correct.
5. Solve the proportion. Round to the nearest hundredth, where necessary.
9/4 = ?/12
A. 54
B. 36
C. 45
D. 27
To solve the proportion, we cross-multiply and solve for the missing value: 9 * 12 = 4 * ?. This gives us 108 = 4x. Dividing both sides by 4, we get x = 27. So the correct answer is D.
Your answer is correct.
6. 27/90 = 3/?
A. 3
B. 10
C. 9
D. 27
To solve the proportion, we cross-multiply and solve for the missing value: 27 * ? = 3 * 90. Simplifying, we get ? = (3 * 90) / 27 = 10. So the correct answer is B.
Your answer is correct.
7. 32/? = 20/25
A. 37
B. 16
C. 26
D. 40
To solve the proportion, we cross-multiply and solve for the missing value: 32 * 25 = 20 * ?. Simplifying, we get ? = (32 * 25) / 20 = 40. So the correct answer is D.
Your answer is correct.
8. Use cross products to determine which of the following pairs of ratios cannot form a proportion.
A. 1/3 x 3/9
B. 2/3 x 4/9
C. 2/3 x 4/6
D. 1/3 x 2/6
To check if two ratios form a proportion, we need to check if the cross products are equal. Let's calculate the cross products for each option:
A. 1/3 x 3/9 = 1/3 * 3/9 = 3/27
C. 2/3 x 4/6 = 2/3 * 4/6 = 8/18
D. 1/3 x 2/6 = 1/3 * 2/6 = 2/18
The only option where the cross products are not equal is option B:
B. 2/3 x 4/9 = 8/27
So the correct answer is B.
Your answer is correct.
You got all the answers correct. Well done! If you have any more questions, feel free to ask.
