Write 872 in expanded form.

Write 872 in expanded form.

• A. 800 + 70 + 2
• B. 872
• C. 800 + 7 + 2
• D. 800 + 70 + 20

Answer: (A)

Expanded form breaks a number into the sum of its place-value parts. In 872, the digit 8 sits in the hundreds place, giving 8 × 100 = 800. The 7 sits in the tens place, giving 7 × 10 = 70. The 2 sits in the ones place, giving 2 × 1 = 2. Put together, 800 + 70 + 2 equals 872, so the expanded form is 800 + 70 + 2. The other options either omit a place value (like forgetting the tens to write 800 + 7 + 2) or misplace a value (writing 20 for the ones place).
