Question

\(\frac{2}{5}+\frac{3}{10}-\frac{1}{2}\)

Giúp mik nhé các bạn!

Answer 1

\(\frac{2}{5}+\frac{3}{10}-\frac{1}{2}=\frac{4}{10}+\frac{3}{10}-\frac{5}{10}=\frac{2}{10}=\frac{1}{5}\)

Answer 2

2/5+3/10-1/2

=4/10+3/10-5/10

=2/10=1/5

Answer 3

$\frac{2}{5}+\frac{3}{10}-\frac{1}{2}=\frac{4}{10}+\frac{3}{10}-\frac{5}{10}=\frac{2}{10}=\frac{1}{5}$

Answer 4

\(\frac{2}{5}+\frac{3}{10}-\frac{1}{2}\)

\(=\frac{4}{10}+\frac{3}{10}-\frac{5}{10}\)

\(=\frac{4+3-5}{10}\)

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

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

Answer 5

\(\frac{2}{5}+\frac{3}{10}-\frac{1}{2}=\frac{4}{10}+\frac{3}{10}-\frac{5}{10}=\frac{12}{10}=\frac{6}{5}\)

Answer 6

\(\frac{2}{5}+\frac{3}{10}-\frac{1}{2}=\frac{4}{10}+\frac{3}{10}-\frac{5}{10}=\frac{7}{10}-\frac{5}{10}=\frac{2}{10}=\frac{1}{5}\)

nhớ ấn đúng cho mình nha

Answer 7

\(\frac{2}{5}+\frac{3}{10}-\frac{1}{2}\)

\(=\frac{4}{10}+\frac{3}{10}-\frac{5}{10}\)

\(=\frac{7}{10}-\frac{5}{10}\)

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

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