We can write 412.638 as
[tex]412.638 = 400 + 10 + 2 + 0.6+0.03+0.008[/tex]
[tex]= 4*10^2 + 10 + 2 + 6*10^{-1}+ 3*10^{-2} + 8*10^{-3}[/tex]
So this is required expanded form of the given number.
[tex]412.638 = 400 + 10 + 2 + 0.6+0.03+0.008[/tex]
[tex]= 4*10^2 + 10 + 2 + 6*10^{-1}+ 3*10^{-2} + 8*10^{-3}[/tex]
So this is required expanded form of the given number.
The correct answer is:
400 + 10 + 2 + 0.6 + 0.03 + 0.008.
Explanation:
To write a number in expanded form, we use place values.
4 is in the hundreds place; this makes its value 400.
1 is in the tens place; this makes its value 10.
2 is in the ones place; this makes its value 2.
6 is in the tenths place; this makes its value 0.6.
3 is in the hundredths place; this makes its value 0.03.
8 is in the thousandths place; this makes its value 0.008.
To write this together, we find the sum:
400 + 10 + 2 + 0.6 + 0.03 + 0.008.
