Correct Answer: B

Rationale:
To determine the greatest value among the choices, you need to convert all options to a common format. In this case, converting fractions to decimals will help compare them. When 7 · 5 is calculated, it equals 1.4, which is greater than 0.729 (choice
C) and 0.78 (choice A when rounded). The percentage 73% (choice
D) is equivalent to 0.73, making 7 · 5 the largest value.
Therefore, the correct answer is B.
Choice A is smaller than B, as 43 · 55 equals approximately 0.78.
Choice C is smaller than B, as 0.729 is less than 1.4.
Choice D is smaller than B, as 73% is equal to 0.73, which is less than 1.4.

Correct Answer: C

Rationale:
To convert a percentage to a decimal, you move the decimal point two places to the left.
Therefore, 87.5% as a decimal is 0.875.
Choice A (875) is incorrect as it represents the percentage without converting to a decimal.
Choice B (8,750) is incorrect as it represents the percentage in whole numbers without decimal conversion.
Choice D (8.75) is incorrect as it represents 875% instead of 87.5%.

Correct Answer: C

Rationale:
To calculate a 16% gratuity on a bill of $58.60, you multiply $58.60 by 0.16, which equals $9.376. Rounding this to the nearest cent gives $9.38.
Therefore, the estimated gratuity is $9.38.
Choice A is incorrect as it does not accurately reflect the calculated amount.
Choice B is also incorrect as it does not match the correct calculation.
Choice D is incorrect as it is not the nearest estimated value to the calculated amount.

Correct Answer: A

Rationale: After the $400 down payment, the remaining balance is $1,170. With monthly payments of $100, it will take 12 months to pay off the remaining balance.
Therefore, the correct answer is 12 months.
Choice B (16) is incorrect as it exceeds the required timeframe.
Choice C (15) is incorrect as it is close but still one month over the correct timeframe.
Choice D (11) is incorrect as it underestimates the time needed to pay off the remaining balance.

Correct Answer: A

Rationale: A quotient is the result of dividing one number by another.
Choice A is correct because it accurately defines a quotient as the outcome of a division operation.
Choice B is incorrect because it describes the result of multiplying two numbers, not dividing them.
Choice C is incorrect because it refers to the remainder of a subtraction operation, not a division.
Choice D is incorrect because it mentions the number remaining after a division, which is typically referred to as the remainder and not the quotient.
