Explain the error pattern on Jon’s test.

a. $\frac{13}{35}=\frac{1}{5},\frac{27}{73}=\frac{2}{3},\frac{16}{64}=\frac{1}{4}$

b. $\frac{4}{5}+\frac{2}{3}=\frac{6}{8},\frac{2}{5}+\frac{3}{4}=\frac{5}{9},\frac{7}{8}+\frac{1}{3}=\frac{8}{11}$

c. $8\frac{3}{8}-6\frac{1}{4}=2\frac{2}{4},5\frac{3}{8}-2\frac{2}{3}=3\frac{1}{5},2\frac{2}{7}-1\frac{1}{3}=1\frac{1}{4}$
