In the number 5,678,912, what is the value of the digit 6?

• A. 60,000
• B. 6,000
• C. 6,000,000
• D. 600,000

Answer: (D)

Understanding place value in large numbers: each digit’s worth depends on its position. In 5,678,912, the digit 6 sits in the hundred-thousands place, which means its value is six hundred thousand. That’s 6 × 100,000 = 600,000. The hundred-thousands place is the second from the left after the millions place, which fits with 5 as the millions digit and 7 as the ten-thousands digit to form the full number. If that 6 were in a different place, its value would be different—for example, in the ten-thousands place it would be 60,000, or in the millions place 6,000,000.
