Answer 1

1) $\frac{3}{5}*\frac{4}{9}+1\frac{1}{3}=\frac{4}{15}+\frac{4}{3}=\frac{24}{15}=1\frac{3}{5}$

2) $1\frac{1}{4}*\frac{2}{5}-\frac{1}{3}=\frac{5}{4}*\frac{2}{5}-\frac{1}{3}=\frac{2}{4}-\frac{1}{3}=\frac{1}{6}$

3) $\frac{3}{8}:\frac{1}{2}+3\frac{1}{4}=\frac{3}{4}+3\frac{1}{4}=4$

4) $\frac{5}{6}:\frac{1}{3}+1\frac{3}{8}=\frac{5}{2}+\frac{11}{8}=\frac{31}{8}=3\frac{7}{8}$

5) $1\frac{2}{5}*\frac{5}{7}+\frac{3}{8}=\frac{7}{5}*\frac{5}{7}+\frac{3}{8}=1\frac{3}{8}$

6) $2\frac{1}{3}:1\frac{5}{9}-\frac{5}{6}=\frac{7}{3}*\frac{9}{14}-\frac{5}{6}=\frac{3}{2}-\frac{5}{6}=\frac{4}{6}=\frac{2}{3}$
