So for multiplication with fractions, it's just multiplying numerators with numerators and denominators with denominators.
[tex] \frac{1}{18} *\frac{4}{5}=\frac{4}{90} [/tex]
From here, it appears that the answer is 4/90, however it can be simplified by dividing both numerator and denominator by 2 as such:
[tex] \frac{4}{90}\div \frac{2}{2} =\frac{2}{45} [/tex]
In short, the answer is 2/45, or C.
