Answer key — Numbers to 1,000,000

1.
70000place-value-million-01
$371{,}502 = 300{,}000 + 70{,}000 + 1{,}000 + 500 + 2$ . The $7$ is in the ten-thousands place, so its value is $\mathbf{70{,}000}$ .
2.
428000place-value-million-02
Standard form: $427{,}508$ (the tens place is $0$ because no tens appear in the expanded form). The thousands digit is $7$ and the next digit is $5$ , so round up: $\mathbf{428{,}000}$ .
3.
(D)
$380{,}000$
place-value-million-03
The ten-thousands digit is $7$ ; the thousands digit is $5$ , so round up to $\mathbf{380{,}000}$ . ( $370{,}000$ rounds down even though the next digit is $5$ ; $400{,}000$ rounds to the nearest hundred thousand; $375{,}000$ is not rounded at all.)
