In this question, if we are trying to identify the positions of the numbers in their respective values in the numerical form. Then we can observe the following:
1. The value of 7 in 503, 497 is ones
2. The value of 7 in 26, 475 is tens
3. The value of 3 in 6, 300 is hundreds
4. The value of 3 in 530 then is tens
Understanding number positions is very vital in knowing the digit in particularity. This benefit will be needed in cases of solving complex and perplex equations and solutions.
