Последовательно вычисляем:
\[\frac{3}{4}+\frac{1}{4}=1.\]
\[1-\frac{1}{5}=\frac{4}{5}.\]
\[\frac{4}{5}-\frac{3}{5}=\frac{1}{5}.\]
\[\frac{1}{5}+\frac{4}{5}=1.\]
\[1-\frac{7}{12}=\frac{5}{12}.\]
\[\frac{5}{12}+\frac{1}{12}=\frac{6}{12}=\frac{1}{2}.\]
\[\frac{1}{2}-\frac{1}{12}=\frac{6}{12}-\frac{1}{12}=\frac{5}{12}.\]
В гусенице: \(1\), \(\frac{4}{5}\), \(\frac{1}{5}\), \(1\), \(\frac{5}{12}\), \(\frac{1}{2}\), \(\frac{5}{12}\).
