there are 3 feet in 1 yard, that is 3ft/1yd or 1yd/3ft
you can use either, now, in this case, we want to convert
from yards to feet, so, that means we want to cancel out
the yards unit, so we use the form with the "yd" at the bottom
of the fraction, so it cancels out with the one above
[tex]\bf 9.4\boxed{yd}\cdot \cfrac{3ft}{1\boxed{yd}}\implies \cfrac{9.4\cdot 3ft}{1}\implies 9.4\cdot 3ft[/tex]
