Answer:

A

Step-by-step explanation:

Every digit of a number has a place value.  Place value is the value represented by a digit in a number based on its position in the number.  

In the number 27,385:

2 is in ten thousands place ⇒ 2 × 10,000 so its place value is 20,000

7 is in thousands place ⇒ 7 × 1,000 so its place value is 7,000

3 is in hundreds place ⇒ 3 × 100 so its place value is 300

8 is in tens place ⇒ 8 × 10 so its place value is 80

5 is in units place so its place value is 5

Therefore,

27,385 = 2 × 10,000 + 7 × 1,000 + 3 × 100 + 8 × 10 + 5

So the answer is A
