Answer:
y^2/x^6
apply exponent rule:
x^-2/x^4=1/x^4-(-2)=y/y^-1 x^4 -(-2)
then you subtract 4-(-2)=6
y/x^6 y^-1
cancel out the common factor: y^-1 and you get
y^2
------
x^6
There are 12 thousands, so we put that in the thousands place
12,000
now add it to 12 in the thousandths place
0.012
12,000.012
