Final answer:
The digit 7 in 477,000 has a place value of 7,000 when considering its position as the third digit from the right in the thousands place, assuming the question refers to the single instance of 7 as it appears in the options given.
Step-by-step explanation:
The value of the digit 7 in the number 477,000 depends on its place value. In this number, we have two 7s, but considering the context provided by the question, which seems to emphasize the 'value' of the 7s collectively in a singular form, the correct place value would be identified by analyzing the digits' positions compared to the decimal point. Since the first 7 comes after the 4 in the ten thousands place, it represents 70,000. However, the second 7 follows the first 7 and is in the thousands place, representing 7,000. Adding these together, we get 77,000, which is the value of the two 7s.
According to place value rules, the value of a digit is determined by its position relative to the decimal point. In this case, the second 7 is in the thousands place, so it alone has a value of 7,000, which is the correct answer to the question considering the options provided.
