• C. 10.507 kg.
  
• D. 0.10507 kg.
  

Answer 1

The correct option is C 10.507 kg.


$\text{Total weight of 10 packets}=105.07kg$

$\text{Weight of each packet}=\frac{105.07}{10}kg$

To convert $\frac{105.07}{10}$ into a decimal, we have to divide 105.07 by 10

$\text{To divide}:\frac{105.07}{10}$
$\Rightarrow$ Write the numerator as 105.07

$\Rightarrow$ Denominator have one zero (10), hence shift the decimal point one place to the left in 105.07 (numerator)

	Thousands	hundreds	ones	.	tenths	hundredths	thousandsths
	1	0	5	.	0	7
$÷$ 10		1	0	.	5	0	7

$\Rightarrow \frac{105.07}{100}=10.507$

The weight of each packet is 10.507 kg.
