\[\textbf{а)}\ \frac{56}{x} = 28\]
\[x = 56\ :28\]
\[x = 2.\]
\[\textbf{б)}\ \frac{y}{16} = 5\]
\[y = 5 \cdot 16\]
\[y = 80.\]
\[\textbf{в)}\ \frac{d - 4}{5} = 12\]
\[d - 4 = 12 \cdot 5\]
\[d - 4 = 60\]
\[d = 60 + 4\]
\[d = 64.\]
\[\textbf{г)}\ \frac{24 + t}{7} = 16\]
\[24 + t = 16 \cdot 7\]
\[24 + t = 112\]
\[t = 112 - 24\]
\[t = 88.\]
