Answer: 8 + 0.5 + 0.04 + 0.002 = 8.542
To expand an number or decimal, add up the values.
In this problem, we're expanding a decimal. To expand a decimal, break the decimal up and add it by its values.
These are the values of the number.
8 is in the ones place.
0.5 is in the tenths place.
0.04 is in the hundredths place.
0.002 is in the thousandths place.
So, with that being said, we'll add up these values.
8 + 0.5 + 0.04 + 0.002 = 8.542!
Hence, 8 + 0.5 + 0.04 + 0.002 is the expanded form of 8.542.
