Question

\(\left(\frac{1}{3}-\frac{1}{5}\right)x\frac{1}{2}\)

Các bạn ơi tính bằng 2 cách đấy nhé !

Answer 1

\(\left(\frac{1}{3}-\frac{1}{5}\right)\times\frac{1}{2}=\frac{1}{6}-\frac{1}{10}\)

                                  \(=\frac{1}{15}\)

\(\left(\frac{1}{3}-\frac{1}{5}\right)\times\frac{1}{2}=\frac{2}{15}\times\frac{1}{2}=\frac{1}{15}\)

Answer 2

(1/3-1/5)x1/2=1/15

1/3x1/2-1/5x1/2=1/15

tk mk nha
