Answer:
The answers are 340 and 0.034.
Step-by-step explanation:
In order to determine the number in the blank position, we have to know the number which are dividing the others.
First number=3,400,00
Second number=34,000
If we divide both number:

So, every number is being divided by 100. Then, the blank numbers are


To check that:
Second number=34,000
Third number (blank position)=340

Third number (blank position)=340
Fourth number=3.4

Fourth number=3.4
Fifth number=0.034

We can see that the number 100 is the constant quotient of every two continuous numbers.
Finally, the blank numbers are 340 and 0.034.
