Answer 1

\(\frac{46}{52}-\frac{15}{26}=\frac{46}{52}-\frac{30}{52}=\frac{16}{52}=\frac{4}{13}\)

Answer 2

\(\frac{15}{26}+\frac{x}{16}=\frac{46}{52}\)

\(\Leftrightarrow\frac{15}{26}+\frac{x}{16}=\frac{23}{26}\)

\(\Leftrightarrow\frac{x}{16}=\frac{23}{26}-\frac{15}{26}\)

\(\Leftrightarrow\frac{x}{16}=\frac{8}{26}=\frac{4}{13}\)

\(\Rightarrow13x=16\times4\)

\(\Rightarrow x=\frac{64}{13}\)
