The number 270,240 in expanded form is broken down by place value:
- **200,000** (hundred thousands place)
- **70,000** (ten thousands place)
- **200** (hundreds place)
- **40** (tens place).

Adding these values:
200,000 + 70,000 = 270,000
270,000 + 200 = 270,200
270,200 + 40 = **270,240**.

**Option C (200,000 + 70,000 + 200 + 40)** matches this breakdown. Other options either omit required place values or include incorrect amounts (e.g., 7,000 instead of 70,000).

270240 = 200000 + 70000 + 200 + 40.
C
minimax The correct answer is:

B. 200,000 + 7,000 + 200 + 40

This is because 270,240 can be broken down into its place values:

- 2 in the hundred thousands place is 200,000
- 7 in the ten thousands place is 70,000
- 0 in the thousands place is 0 (but it's not shown in the expanded form as it's zero)
- 2 in the hundreds place is 200
- 4 in the tens place is 40

Adding these up gives us 270,240.

kimi The correct expanded form of 270,240 is:

200,000 + 70,000 + 200 + 40

So the answer is C.

Explanation:
Expanded form means writing a number as the sum of each of its place values.
In the number 270,240:
- The 2 is in the hundred thousands place, so it represents 200,000.
- The 7 is in the thousands place, so it represents 7,000.
- The first 0 is in the hundreds place, so it represents 0. We don't write anything for this in expanded form because it's zero.
- The 2 is in the tens place, so it represents 20.
- The 4 is in the ones place, so it represents 4.
Adding these together, we get: 200,000 + 7,000 + 20 + 4.
However, since the tens place is 2, it should represent 20, not 2 as written in the original options. Among the given options, B is the closest with a small correction: 200,000 + 7,000 + 200 + 40. Here, the tens place is correctly represented as 200 (which is equivalent to 2 tens times 10) and the ones place is represented as 40 instead of 4, which is a bit of an anomaly, but it's likely a typo in the options since all other place values are correctly represented. If we consider this correction, then option B accurately represents the expanded form of 270,240.

Note: Technically, the correct expanded form should be 200,000 + 70,000 + 20 + 4, but since 20 is represented as 200 in option B (likely due to a typo) and 4 is represented as 40, we choose B as the closest match given the available options. If we strictly follow the place values, then none of the options are entirely correct.

The expanded form of 270,240 is:

200,000 (two hundred thousand) + 70,000 (seventy thousand) + 2,000 (two thousand) + 40 (forty).

Thus, the correct choice is D.

deepseekv3 To express 270,240 in expanded form, break it down into its place values:

- **200,000** (hundred thousands place)
- **70,000** (ten thousands place)
- **200** (hundreds place)
- **40** (tens place)

So, the expanded form is:
**200,000 + 70,000 + 200 + 40**

The correct answer is **C**.
