5003 Praxis Practice Test Practice Question
Which of the following mental computations gives the closest estimate of the answer to the preceding problem?
Correct Answer: A
Rationale: Option A, dividing 480 by 8, yields 60, which closely approximates the target value of 60, making it the most accurate estimate.
Option B, dividing 480 by 10, results in 48, which is significantly lower than the target.
Option C, dividing 490 by 7, gives approximately 70, which is higher than the target and less relevant.
Option D, dividing 490 by 10, results in 49, also lower than the target and not as close as option A.
Thus, option A provides the best estimate for the problem at hand.
