Question

Read and expand the numbers wherever there are blanks.

Number	Number name	Expansion
3,00,000	Three lakhs	\[3\times 1,00,000\]
3,50,000	Three lakhs fifty thousand	\[3\times 1,00,000+5\times 10,000\]
3,53,500	Three lakhs fifty-three thousand five hundred	\[3\times 1,00,000+5\times 10,000+3\times 1000+5\times 100\]
4,57,928
4,07,928
4,00,829
4,00,029

Answer 1

Hint: To solve the question, we have to name the given number as the examples mentioned by mentioning the digits of the respective places. But if there is digit 0 in the given number it should not be named since naming the place of digit 0, when it is present in between nonzero digits, is not a standard of naming a number. Thus, such naming error mistakes should be avoided. To solve the expansion, we have to multiply the digits with the value of respective places.

Complete step-by-step answer:
The given number is 4,57,928.
The name of the given number is four lakhs fifty-seven thousand nine hundred twenty-eight.
The expansion of the given number is \[4\times 1,00,000+5\times 10,000+7\times 1000+9\times 100+2\times 10+8\]
The given number is 4,07,928.
The name of the given number is four lakhs seven thousand nine hundred twenty-eight.
The expansion of the given number is \[4\times 1,00,000+0\times 10,000+7\times 1000+9\times 100+2\times 10+8\]
The given number is 4,00,829.
The name of the given number is four lakhs eight hundred twenty-nine.
The expansion of the given number is \[4\times 1,00,000+0\times 10,000+0\times 1000+8\times 100+2\times 10+9\]
The given number is 4,00,029.
The name of the given number is four lakhs twenty-eight.
The expansion of the given number is \[4\times 1,00,000+0\times 10,000+0\times 1000+0\times 100+2\times 10+9\]
Thus, the given table with complete information is

Number	Number name	Expansion
3,00,000	Three lakhs	\[3\times 1,00,000\]
3,50,000	Three lakhs fifty thousand	\[3\times 1,00,000+5\times 10,000\]
3,53,500	Three lakhs fifty-three thousand five hundred	\[3\times 1,00,000+5\times 10,000+3\times 1000+5\times 100\]
4,57,928	Four lakhs fifty-seven thousand nine hundred twenty-eight	\[4\times 1,00,000+5\times 10,000+7\times 1000+9\times 100+2\times 10+8\]
4,07,928	Four lakhs seven thousand nine hundred twenty-eight	\[4\times 1,00,000+0\times 10,000+7\times 1000+9\times 100+2\times 10+8\]
4,00,829	Four lakhs eight hundred twenty-nine	\[4\times 1,00,000+0\times 10,000+0\times 1000+8\times 100+2\times 10+9\]
4,00,029	Four lakhs twenty-eight	\[4\times 1,00,000+0\times 10,000+0\times 1000+0\times 100+2\times 10+9\]

Note: The possibility of mistake can be, the naming of the given number, if there is digit 0 in the given number it should not be named since naming the place of digit 0, when it is present in between nonzero digits, is not a standard of naming a number. Thus, such naming error mistakes should be avoided. The other possibility of mistake can be not mentioning the place of digit 0 in the expansion, which should be avoided since the digit indicates the value of the given number.
