Explanation
You have far too many fractions to add quickly with the Bowtie. Instead, convert all of the fractions to the common denominator of 48:
\(\frac{1}{48}+\frac{1}{48}+ \frac{1}{12}+\frac{1}{8}+\frac{1}{4}+\frac{1}{2}\).
\(\frac{1+1+4+6+12+24}{48}\).
\(\frac{48}{48}\) = 1
Hence option B is correct.
