Cách 1
\(\left(\frac{2}{3}-\frac{1}{4}\right)\cdot\frac{1}{2}=\left(\frac{8}{12}-\frac{3}{12}\right)\cdot\frac{1}{2}=\frac{5}{12}\cdot\frac{1}{2}=\frac{5}{24}\)
Cách 2\(\left(\frac{2}{3}-\frac{1}{4}\right)\cdot\frac{1}{2}=\frac{2}{3}\cdot\frac{1}{2}-\frac{1}{4}\cdot\frac{1}{2}=\frac{1}{3}-\frac{1}{8}=\frac{8}{24}-\frac{3}{24}=\frac{5}{24}\)
Cách 1 : (2/3 - 1/4) x 1/2
= 5/12 x 1/2
= 5/24
Cách 2 : (2/3 - 1/4) x 1/2
= 2/3 x 1/2 - 1/4 x 1/2
= 1/3 - 1/8
= 5/24
kb vs tớ nha
Cách 1:(2/3-1/4)x1/2
=5/12x1/2
=5/24
Cách 2:(2/3-1/4)x1/2
=2/3x1/2-1/4x1/2
=2/6-1/8
=5/24
k đúng cho mình nha
