Question

7/15+2/10=... | Viết kết quả dưới dạng phân số tối giản|

Answer 1

\(\frac{7}{15}+\frac{2}{10}\)

\(=\frac{7}{15}+\frac{1}{5}\)

=\(\frac{7}{15}+\frac{3}{15}\)

=\(\frac{10}{15}\)

=\(\frac{2}{3}\)

Answer 2

\(\frac{7}{15}+\frac{2}{10}\)

\(=\frac{7}{15}+\frac{1}{5}\)

\(=\frac{7}{15}+\frac{3}{15}\)

\(=\frac{10}{15}=\frac{2}{3}\)

Answer 3

\(\frac{7}{5}+\frac{2}{10}=\frac{70}{50}+\frac{10}{50}=\frac{80}{50}=\frac{8}{5}\)\(\frac{8}{5}\)

Answer 4

\(\frac{7}{15}+\frac{2}{10}=\frac{7}{15}+\frac{1}{5}=\frac{7}{15}+\frac{3}{15}=\frac{10}{15}=\frac{2}{3}=0,6\)

Answer 5

 \(=\frac{8}{5}\)
