Answer:
Option B and C are correct.
[tex]8 \times 100 + 4 \times 10 +2 \times \frac{1}{100}[/tex]
[tex]8 \times 100 + 4 \times 10 + 0 \times 1 + 0 \times\frac{1}{10}+2 \times \frac{1}{100}[/tex]
Step-by-step explanation:
Find the expanded form of 840.02.
Any decimal number can be expanded in the form of power of 10.
then;
In 840.02
the first 8 is
8 hundreds i.e, 800 ,
4 is 4 tens i.,e 40 ,
0 ones ,
0 one-tenths and
2 hundredths,
we can write this as;
[tex]840.02 = 800 + 40 + 0 \times 1 + 0 \times \frac{1}{10}+2 \times \frac{1}{100}[/tex]
or
[tex]8 \times 100 + 4 \times 10 +2 \times \frac{1}{100}[/tex]
or
[tex]840.02 = 8 \times 100 + 4 \times 10 + 0 \times 1 + \frac{0}{10}+ \frac{2}{10^2}[/tex]
