write each decimal in standard form, expanded form, and word form.
12+0.2+0.005
12.205
twelve and two hundred five thousandths
To write each decimal in standard form, expanded form, and word form, let's start by breaking down the given decimal, 12 + 0.2 + 0.005, into its individual parts.
1. Standard Form:
To write in standard form, we add up the decimal values: 12 + 0.2 + 0.005 = 12.205.
2. Expanded Form:
To write in expanded form, we express each decimal place value separately:
12 (tens) + 0.2 (tenths) + 0.005 (thousandths)
So, in expanded form: 12 + 0.2 + 0.005 = 10 + 2 + 0.2 + 0.005.
3. Word Form:
To write in word form, we express the value in words:
12 is written as "twelve",
0.2 is written as "two tenths",
0.005 is written as "five thousandths".
So, in word form: 12 + 0.2 + 0.005 = "twelve and two tenths and five thousandths".
