Answer 2

Answer:

The number 20,005 can be read as twenty thousand five.

The expansion of 20,005 is 20,000 + 5.

Step-by-step explanation:

The number 20,005 can be read as twenty thousand five.

Concept,

A number can be expressed as the sum of its place value.

For example, consider five digit largest number

i.e. 99,999.

Here, the place value of '9' in the rightmost corner of the number 99,999 is 1 × 9, the place value of the next '9' is 90, the place value of the third '9' is 900, the place value of penultimate '9' is 9,000, and the place value of leftmost corner '9' is 90,000.

Hence, the expansion of 99,999 = the sum of the place values of all 9's.

Therefore, 99,999 = 90,000 + 9,000 + 900 + 90 + 9

Calculation,

Applying a similar concept for the expansion of 20,005.

i.e. the expansion of 20,005 is:

2(10,000) + 0(1,000) + 0(100) + 0(10) + 1(5) = 20,005.

⇒ Expansion of 20,005 = 20,000 + 5
