Mr. Aronson noticed that one of his students, Wesley, incorrectly solved a multiplication problem, as represented in the work shown. Which of the following student work samples shows incorrect work that is most similar to the preceding work?

A. 23×41=64+120=184
B. 57×69=126+320=446
C.42×58=100+240=340
D.68×79=146+280=426

Answer 1

The student's work sample that is most similar to Wesley's incorrect work is option D: 68×79=146+280=426.

Step-by-step explanation:

The student's work sample that is most similar to Wesley's incorrect work is option D: 68×79=146+280=426.

Wesley made the mistake of adding the partial products instead of multiplying them. In option D, the student also adds the partial products instead of multiplying them, resulting in an incorrect sum.

To solve the multiplication problem correctly, Wesley should have multiplied 34 by 52, which is 1768.
