giúp với

Answer 1

a) \(\frac{1}{8}+\frac{3}{5}=\frac{5+24}{40}=\frac{29}{40}\)

b) \(\frac{6}{35}.\frac{49}{54}+\frac{1}{3}=\frac{6.7.7}{5.7.6.9}+\frac{1}{3}=\frac{7}{45}+\frac{1}{3}=\frac{7}{45}+\frac{15}{45}=\frac{22}{45}\)

c) \(\frac{4}{5}:\frac{3}{4}+0,25=\frac{4}{5}.\frac{4}{3}+\frac{25}{100}=\frac{16}{15}+\frac{1}{4}=\frac{64+15}{60}=\frac{79}{60}\)
