3)place value: hundredth||| value: 0.04

4)place value: ten thousandth||| value: 0.0001

5)place value: thousandth||| value: 0.002

explanation:

consider a number is like a word:

"idea" is a word of four

if we count from the right side.

'a' is letter one.

'd' is letter two.

'e' is letter three.

'a' is letter four.

same idea for numbers and digits.

123456 is a number of 6-digits.

when they ask for "place value" they mean in terms of "tens", meaning:

any number less than 10, considered as "ones"

any number less than 100,  is considered as "tens"

any number less than 1000, is considered as "hundreds"

same idea when we go from the point to the right (fractions). but we start directly from "tens" and skip/ignore the "ones".

but instead of 's' we put 'th'

Example: ten(th), hundred(th)...

search on youtube this song, will help you a lot to memorize that: (it also got captions)

but "value" means:

value of each digit in a number. how many does that number represent?

For example, the 5 in 350 represents 5 tens, or 50(as 5×10=50); however, the 5 in 5,006 represents 5 thousands, or 5,000.
