Answer:
see the procedure
Explanation:
we know that
![1.8=1+0.8](https://img.qammunity.org/2020/formulas/mathematics/middle-school/pw4eq4ynsxrn1738ny40pjk1b1lo6lo229.png)
![486=400+80+6](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tots5zkudnt0563v0fxilrt7knm3qw2fjp.png)
so
The value of digit 8 in 1.8 is 0.8
The value of digit 8 in 486 is 80
Divide the numbers
80/0.8=100
therefore
The value of the digit 8 in 486 is 100 times greater than the value of digit 8 in 1.8
or
The value of the digit 8 in 1.8 is 100 times less than the value of digit 8 in 486
