Question

Answer 1

We use the decimal, base 10, system of counting.

Each column (or place) represents a different power of 10, as follows. where 10^-n is same as ¹/₁₀ⁿ

etc <---- 10⁴ ----- 10³ ------ 10² ----- 10¹ ---- 10⁰ ---- 10^-1------ 10^-2 ------ 10^-3 ---- 10^-4 ----> etc

value-----10000 --1000------100-------10--------1----------0.1--------0.01------0.001 ---- 0.0001

eg 230 ----------------------------2----------3----------0

place value of 2 = 2 x100 and 3 = 3 x10

or 230 = 200 + 30

eg 56.7 ---------------------------------------5----------6----------7

place value of 5 = 5 x10 and 6 = 6 x1 and 7 x 0.1

or 56.7 = 50 + 6 + 0.7

not sure of your specified number, but I think you mean:

--------------------------------------4-----------7---------4-----------0----------3 ----------9

this is 474.039

place value of first 4 is 4 x 100 = 400

7 is 7 x 10 = 70

second 4 is 4 x 1 = 4

you must have a 0 in 1/10 place but value is 0

3 x hundreths = 3/100 or 0.03

9 x thousands = 9/1000 or 0.009

or 474.039 = 400 + 70 + 4 + 0.03 + 0.009

The key is that we use the same digits (0-9) to write a number, and the same digit can be used several times. But its place value depends on which power of 10 it is. In other words, a 2 is not the same as another 2, because of the different power. In your number, there are two 4s, but one is "worth" 400 but the other is just 4.
