Question 1 of 5
A die is rolled. What is the probability of getting 5?
Correct Answer: A
Rationale: The correct answer is A: 16.67%. There is only one face of the die with a 5, out of a total of 6 faces. Therefore, the probability of rolling a 5 is 1/6, which is approximately 16.67%. Other choices are incorrect: B: 20% - This is the probability if there were 5 faces with a 5. C: 50% - This would be the probability if there were only two faces on the die. D: 83.33% - This would be the probability if there were 5 faces with a 5.
Question 2 of 5
Convert 7/8 to a decimal.
Correct Answer: C
Rationale: To convert 7/8 to a decimal, you divide 7 by 8. 7 divided by 8 equals 0.875. Therefore, the correct answer is C: 0.875. Option A and B are incorrect as they are the same and represent 0.8, not 0.875. Option D is incorrect as 7/8 is not equal to 0.9.
Question 3 of 5
How many inches are in 3.5 yards?
Correct Answer: A
Rationale: To convert yards to inches, we use the fact that 1 yard is equal to 36 inches. Therefore, to find how many inches are in 3.5 yards, we multiply 3.5 by 36, which equals 126 inches. Choice A (126 inches) is correct. Choices B, C, and D are incorrect as they do not correctly calculate the conversion from yards to inches. B (144 inches) is the result of multiplying 3.5 by 40 instead of 36. C (132 inches) is the result of multiplying 3.5 by 38. D (120 inches) is the result of multiplying 3.5 by 34.
Question 4 of 5
A die is rolled. What is the probability of getting 5?
Correct Answer: A
Rationale: The correct answer is A: 16.67%. There is only one face of the die with a 5, out of a total of 6 faces. Therefore, the probability of rolling a 5 is 1/6, which is approximately 16.67%. Other choices are incorrect: B: 20% - This is the probability if there were 5 faces with a 5. C: 50% - This would be the probability if there were only two faces on the die. D: 83.33% - This would be the probability if there were 5 faces with a 5.
Question 5 of 5
How many grams are in 7 kilograms?
Correct Answer: A
Rationale: To convert kilograms to grams, we need to multiply by 1000 because there are 1000 grams in a kilogram. Therefore, 7 kilograms x 1000 = 7000 grams. Choice A is correct. Choices B, C, and D are incorrect because they do not correctly convert kilograms to grams. B is too small, C is one decimal place off, and D is too large.
