B. Yes, because both numbers have a 6, so the values are equal.

A student wrote 745,206 as:

(7 × 100,000) + (4 × 10,000) + (5 × 1,000) + (2 × 10) + (6 × 1)

Is the student correct? Explain why or why not.

The student wrote 2 × 10, which equals 20, but in 745,206, the 2 is in the hundreds place, so its value is 200.

The correct expanded form is:

(7 × 100,000) + (4 × 10,000) + (5 × 1,000) + (2 × 100) + (6 × 1)

The student’s answer would make the number 745,026, not 745,206.
