Question 1 of 5
Ratio and Proportion: 100:2 :: 60:X. Find X.
Correct Answer: A
Rationale: To find the value of X when the ratio 100:2 is equivalent to 60:X, set up the proportion: 100/2 = 60/X. Cross-multiply to get 100X = 120. Divide by 100 to isolate X, so X = 120/100 = 1.2. Therefore, X equals 1.2, and the correct answer is A. In this scenario, the correct answer is calculated through cross-multiplication of the given ratio and solving for the unknown value. This method is commonly used to solve ratio and proportion problems. It is essential to understand the concept of ratios and proportions to solve mathematical problems efficiently.
Question 2 of 5
Ratio and Proportion: 4:10 :: 5:X
Correct Answer: C
Rationale: To solve for X in the given ratio and proportion, set up the proportion: (4/10) = (5/X). Cross-multiply to get 4X = 50, leading to X = 12.5. So, the correct answer is X = 12.5, making choice C the correct option.
Question 3 of 5
Convert 7/10 to a decimal.
Correct Answer: A
Rationale: To convert a fraction to a decimal, divide the numerator by the denominator. In this case, 7 � 10 = 0.7. Dividing by 10 shifts the decimal point one place to the left, making the conversion straightforward. Therefore, the correct decimal form of 7/10 is 0.7.
Question 4 of 5
Change 0.004 to a ratio.
Correct Answer: C
Rationale: To convert 0.004 to a ratio, you first express it as a fraction, which is 4/1000. Simplifying this fraction gives 1/250. Therefore, the correct ratio for 0.004 is 1:250. This ratio represents the relationship between the parts, where for every 1 unit in the first part, there are 250 units in the second part. It's essential to simplify fractions to their lowest terms to express the ratio in its simplest form.
Question 5 of 5
Convert 5 3/4 to a decimal. Round to the nearest tenth.
Correct Answer: A
Rationale: To convert a mixed number to a decimal, divide the numerator by the denominator. In this case, 3 � 4 = 0.75. Adding this to 5 gives us 5.75. Rounding 5.75 to the nearest tenth results in 5.8. Therefore, the correct answer is A, 5.8.
