7. For each fraction, write an equivalent fraction with the given de a. \( \frac{1}{5}=\frac{1}{15} \) b. \( \frac{3}{6}=\frac{2}{24} \) c. \( \frac{4}{2}=\frac{1}{12} \) d. \( \frac{6}{7}=\frac{2}{28} \) e. \( \frac{5}{8}=\frac{\pi}{32} \)

A set of eight cards were labeled with \( A, D \) \( S=\{A, D, D, I, I, N, O, T\} \) \( S=\{A, D, I, T, O, N\} \) \( S=\{A, I, O\} \) \( S=\{D, I\} \)

Why does ionization energy decrease moving down a group in the periodic table? because effective nuclear charge increases because the outer electrons get further from the nucleus because nuclear charge decreases because the atoms get closer to noble gas configuration
