6. To find the unit rate, divide the number of Oreos by the cost: 100/10. Simplifying this fraction, we get 10. Therefore, the unit rate is A: $1.00.
7. To determine the better deal for Oreos, compare the unit rates. The unit rate for the first deal is $0.18 per Oreo, and the unit rate for the second deal is $0.12 per Oreo. Therefore, the answer is B: 30 Oreos for $3.60.
8. To form a proportion with 20/24, the ratio should be equivalent when simplified to its simplest form. The ratio 3/4 is equal to 20/24 when simplified, so the answer is A: 3/4.
9. To determine which ratios can form a proportion, you need to check if they are equivalent when simplified to their simplest form. The ratio 4/10 is equivalent to 2/5, and the ratio 6/15 is equivalent to 2/5 as well. Therefore, the answer is A: 4/10, 6/15.
10. There is no question number 10 in the given text.
11. To calculate the missing value, cross-multiply. Multiply 4 miles by 27 hours and then divide by 12 miles to find the missing value, h hours. This gives us (4 x 27) / 12 = 9. Therefore, the answer is C: 9.
12. To find the value of x, set up a proportion by equating the ratios of the corresponding sides of the squares. This gives us 8/5 = x/3. Solving for x by cross-multiplication, we get (3 x 8) / 5 = 24 / 5 = 4.8. Therefore, the answer is B: 4.8.
13. To find the distance on the map, multiply the actual distance by the scale factor: 50 miles x (1 in / 10 miles). Simplifying this fraction, we get 5 inches. Therefore, the answer is C: 5 inches.
14. To find the value of x, cross-multiply. Multiply 4.3 by x and then divide by 3.6 to find x. This gives us (4.3 x x) / 3.6 = 21.5. Simplifying this equation, we get 1.194x = 21.5. Dividing both sides by 1.194, we find x ≈ 17.94.
Therefore, the answer is C: 17.4 (rounded to the nearest tenth).
15. To find the ratio of turkeys to acres, divide the number of turkeys by the number of acres: 12/8. Simplifying this ratio, we get 3/2. Then, multiply the ratio by the number of acres of land you want to find the number of turkeys: (3/2) x 64 = 96. Therefore, the answer is C: 96.
1. To find the ratio of cows to chickens, we divide the number of cows by the number of chickens: 20/35 = 4/7. So the answer is A: 4/7.
2. There are three correct ways to write the ratio:
- A: 10:5, 10 to 5, 10/5
- C: 5:10, 5 to 10, 5/10
- D: 5 to 15, 5:15, 5/15
3. To find a ratio equal to 9:36, we divide both numbers by their greatest common divisor (which is 9): 9/9 = 1 and 36/9 = 4. So the answer is B: 1:4.
4. To find the ratio of pies Mrs. Lewis baked to Mrs. Chrisman, we divide the number of pies Mrs. Lewis baked by the number of pies Mrs. Chrisman baked: 6/10 = 3/5. So the answer is C: 3/5.
5. To find the unit rate, we divide the total number of Oreos by the total cost: 30 Oreos / $3.60 = $0.12/Oreo. So the answer is D: $0.12.
6. To find the unit rate, we divide the total number of Oreos by the total cost: 100 Oreos / $10.00 = $1.00/Oreo. So the answer is A: $1.00.
7. To determine which deal is better, we compare the unit rates. The unit rate for option A is $1.00/Oreo and the unit rate for option B is $0.12/Oreo. The lower the unit rate, the better the deal. So the better deal is B: 30 Oreos for $3.60.
8. To form a proportion with 20/24, we need to simplify the ratio. The simplified ratio is 5/6. So the answer is C: 5/6.
9. To form a proportion, the ratio of one pair of numbers needs to be equal to the ratio of the other pair of numbers. In this case, option C: 4/5, 6/7 forms a proportion since 4/5 = 6/7.
11. To solve for h, we can set up a proportion using the given ratio: 12 miles/27 hours = 4 miles/h hours. Cross-multiplying, we get: 12h = 27 * 4. Dividing both sides by 12, we find h = 9. So the answer is C: 9.
12. We can set up a proportion to find the value of x: 8/x = 5/3. Cross-multiplying, we get: 3 * 8 = 5 * x. Simplifying, we find 24 = 5x. Dividing both sides by 5, we find x = 4.8. So the answer is B: 4.8.
13. To find the distance between the cities on the map, we divide the actual distance (50 miles) by the scale (1 inch = 10 miles): 50 miles / 10 miles/inch = 5 inches. So the answer is C: 5 inches.
14. To find the value of x in the ratio, we cross-multiply and then solve for x. The equation becomes: 3.6 * 21.5 = 4.3 * x. Simplifying, 77.4 = 4.3x. Dividing both sides by 4.3, we find x = 18. So the answer is B: 18.
15. To find the number of turkeys on 64 acres, we set up a proportion: 12 turkeys / 8 acres = x turkeys / 64 acres. Cross-multiplying, we get: 12 * 64 = 8 * x. Simplifying, we find 768 = 8x. Dividing both sides by 8, we find x = 96. So the answer is C: 96.
