Question

Cộng phân số;

\(\frac{1}{6}+\frac{5}{6}\)

\(\frac{25}{5}+\frac{2}{6}\)

\(\frac{12}{5}+\frac{6}{9}\)

Answer 1

\(\frac{1}{6}+\frac{5}{6}=\frac{6}{6}=1\)

\(\frac{25}{5}+\frac{2}{6}=\frac{150}{30}+\frac{10}{30}=\frac{160}{30}=\frac{32}{6}=\frac{16}{3}\)

\(\frac{12}{5}+\frac{6}{9}=\frac{108}{45}+\frac{30}{45}=\frac{138}{45}\)

Answer 2

\(\frac{11}{6}\)

\(\frac{16}{3}\)

\(\frac{46}{3}\)

Answer 3

\(\frac{1}{6}+\frac{5}{6}=\frac{6}{6}=1\)

\(\frac{25}{5}+\frac{2}{6}=\frac{150}{30}+\frac{10}{30}=\frac{16}{3}\)

\(\frac{12}{5}+\frac{6}{9}=\frac{12}{5}+\frac{2}{3}=\frac{36}{15}+\frac{10}{15}=\frac{46}{15}\)

Answer 4

\(\frac{1}{6}+\frac{5}{6}=\frac{6}{6}=1\)

\(\frac{25}{5}+\frac{2}{6}=\frac{150}{30}+\frac{10}{30}=\frac{16}{3}\)

\(\frac{12}{5}+\frac{6}{9}=\frac{12}{5}+\frac{2}{3}=\frac{36}{15}+\frac{10}{15}=\frac{46}{15}\)

Answer 5

\(\frac{1}{6}+\frac{5}{6}=\frac{1+5}{6}=1\)

\(\frac{25}{5}+\frac{2}{6}=5+\frac{1}{3}=\frac{16}{3}\)

\(\frac{12}{5}+\frac{6}{9}=\frac{12}{5}+\frac{2}{3}=\frac{36}{15}+\frac{10}{15}=\frac{46}{15}\)

Answer 6

1/6 + 5/6 = 1

25/5 + 2/6 = 16/3

12/5 + 6/9 = 46/15
