Explanation:
The value of a given digit in a number can be found by setting the other digits to zero.
The value of the 3 in 0.931 is 0.030.
The value of the 3 in 0.384 is 0.300.
You want to answer the question ...
... 0.030 = what × 0.300
Divide by 0.300 ...
... 0.030/0.300 = what = 0.1
The value of the 3 in 0.931 is 0.1 = 1/10 times the value of the 3 in 0.384.
