\(\frac{1}{2}+\frac{1}{3}+\frac{1}{2}+\frac{1}{3}\)
= \(\left(\frac{1}{2}+\frac{1}{2}\right)+\left(\frac{1}{3}+\frac{1}{3}\right)\)
= 1 + \(\frac{2}{3}\)
= \(\frac{5}{3}\)
Nếu mình đúng thì các bạn k mình nhé
Bằng 5 / 3 nhé bn mình nhanh nhất k mình nhé
1/2 + 1/3 + 1/2 + 1/3
= 1/2 x 2 + 1/3 x 2
= 5/3
\(\frac{1}{2}+\frac{1}{3}+\frac{1}{2}+\frac{1}{3}\)
\(=\frac{1}{2}x2+\frac{1}{3}x2\)
\(=\frac{2}{2}+\frac{2}{3}\)
\(=\frac{6}{6}+\frac{4}{6}\)
\(=\frac{10}{6}=\frac{5}{3}\)
\(\frac{1}{2}+\frac{1}{3}+\frac{1}{2}+\frac{1}{3}\)
\(=\left(\frac{1}{2}+\frac{1}{2}\right)+\left(\frac{1}{3}+\frac{1}{3}\right)\)
\(=\frac{1}{2}\times2+\frac{1}{3}\times2\)
\(=2\times\left(\frac{1}{2}+\frac{1}{3}\right)\)
\(=2\times\left(\frac{3}{6}+\frac{2}{6}\right)\)
\(=2\times\frac{5}{6}\)
\(=\frac{5}{3}\)
1/2+1/3+1/2+1/3=(1/2+1/2)+(1/3+1/3)
=1/4+1/6
=6/24=4/24=8/24
1/2+1/3+1/2+1/3
=(1/2+1/2)+(1/3+1/3)
=1+2/3
=5/3
Neu dung thi cac ban k minh nhe!
1/2 + 1/3 + 1/2 + 1/3
= ( 1/2 + 1/2 ) + ( 1/3 + 1/3 )
= 1 + 2/3
= 5/3
\(\frac{1}{2}+\frac{1}{3}+\frac{1}{2}+\frac{1}{3}=\frac{5}{3}\)
