Praxis 5025 Practice Question
A student calculates the sum of 4.5 and .923 to be .968. Based on the student’s answer, which of the following best explains the student’s error?
Correct Answer: A
Rationale: The student's answer of .968 suggests a misplacement of the decimal point, as the correct sum of 4.5 and .923 is 5.423.
Option A accurately identifies that the decimal was incorrectly placed in the answer, leading to a significantly lower result.
Option B is incorrect because the student was attempting to add, not subtract.
Option C is also not applicable, as both numbers were in the same decimal format, allowing for proper addition.
Option D does not apply here, as there is no evidence of a regrouping error; the main issue lies in the decimal placement.
