Answer:
It is 1/10th as big as the number to it's left.
Explanation:
To find this, start by isolating the numbers by turning every number other than the one we are looking to find the value of.
6,666.666 = 0,600.000 = 600
6,666.666 = 6,000.000 = 6,000
Now to find how much more it is worth, divide the first by the second.
600/6,000 = 1/10
