Given the numbers:
23.5
164.38
209.105
Write in expanded form and word form.
Solution:
In order to write in expanded form, simply count the number of zeros and non zeros excluding the final digit and the decimals. The non-zero number excluding the last digit will be written in decimal point.
23.5
= 2.35 x 10
Twenty-three point five.
164.39
= 1.6438 x 10^2
One hundred sixty-four point thirty-nine
209.10
= 2.0910 x 10^2
Two hundred nine point ten.
