Question 1 of 5
Ratio and Proportion: 9 : X :: 5 : 300
Correct Answer: A
Rationale: To find the value of X, set up the proportion: 9/X = 5/300. Cross-multiply to get 9 * 300 = 5 * X. Solve for X by dividing 2700 by 5, which equals 540. Therefore, the correct answer is A, which is 540.
Question 2 of 5
What is 7/8 + 9/10 + 6/5 as a mixed number?
Correct Answer: A
Rationale: To add these fractions, first find a common denominator, which is 40 in this case. The fractions are then converted to have a denominator of 40: 35/40 + 36/40 + 48/40 = 119/40. On simplification, 119/40 equals 2 39/40. However, to express it as a mixed number, divide 119 by 40 to get 2 with a remainder of 39. Therefore, the correct mixed number form is 3 22/23.
Question 3 of 5
A new mother changes her baby's diaper 6 times a day, on average. How many diapers will the child use in a year?
Correct Answer: A
Rationale: To calculate the total number of diapers used in a year, you need to multiply the daily diaper changes (6 diapers) by the number of days in a year (365): 6 � 365 = 2,190. Therefore, the correct answer is 2,190 diapers.
Question 4 of 5
Convert 0.60 to a ratio in simplest form.
Correct Answer: A
Rationale: To convert 0.60 to a ratio, start by expressing it as a fraction: 0.60 = 60/100. Then simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 20 in this case. Dividing 60 by 20 gives 3, and dividing 100 by 20 gives 5. Therefore, the simplified fraction is 3/5, which translates to the ratio 3:5 in simplest form.
Question 5 of 5
Which of the following decimals is the largest?
Correct Answer: D
Rationale: To determine the largest decimal among the options, you need to compare them by looking at the digits after the decimal point. When comparing 0.6, 0.667, 0.0688, and 0.68, consider that 0.6 is equivalent to 0.600, 0.667 remains 0.667, 0.0688 is already in its most precise form, and 0.68 is the same as 0.680. By comparing them, you can see that 0.68 is the largest decimal among the options provided. Remember, when comparing decimals, it's important to line up the decimal points to make accurate comparisons.
