Final answer:
The number 215 has a 2 with a value of 200, which is ten times greater than the 2 in 5,621, which has a value of 20.
Step-by-step explanation:
The student is asking which number has a 2 with a value ten times greater than the 2 in 5,621. In 5,621, the 2 is in the tens place, which gives it a value of 20. To find a 2 that has a value ten times greater, we need to locate it in the hundreds place, so it would have a value of 200.
Looking at the options provided:
- 215 - The 2 is in the hundreds place, which is correct, but the value of that 2 is 200, making it the right answer.
- 2,845 - The 2 is in the thousands place, so its value is 2,000, which is too high.
- 52,406 - The 2 is in the ten thousands place, so its value is 20,000, which is again too high.
- 201,384 - The 2 is in the hundred thousands place, which has a value of 200,000, much too high.
Therefore, the answer to the student's question is 215.
