Question

1/2 -1/3 =

1/2 +1/3=

1/2 nhân 1/3=

1/2 : 1/3=

Answer 1

1/2 + 1/3 = 3/6 + 2/6 = 5/6

1/2 - 1/3 = 3/6 - 2/6 = 1/6

1/2 x 1/3 = 1/6

1/2 : 1/3 = 1/2 x 3/1 = 3/2

Chúc bạn hok tốt nha!

Answer 2

\(\frac{1}{2}_{ }-\frac{1}{3}=\frac{3}{6}-\frac{2}{6}=\frac{1}{6}.\)

Answer 3

\(\frac{1}{2}+\frac{1}{3}=\frac{2}{6}+\frac{3}{6}=\frac{5}{6}\)

Answer 4

\(\frac{1}{2}-\frac{1}{3}=\frac{3}{6}-\frac{2}{6}=\frac{1}{6}\)

\(\frac{1}{2}+\frac{1}{3}=\frac{3}{6}+\frac{2}{6}=\frac{5}{6}\)

\(\frac{1}{2}\times\frac{1}{3}=\frac{1}{6}\)

\(\frac{1}{2}:\frac{1}{3}=\frac{3}{2}\)

Answer 5

\(\frac{1}{2}+\frac{1}{3}=\frac{3}{6}+\frac{2}{6}=\frac{5}{6}\)\(\frac{1}{2}.\frac{1}{3}=\frac{3}{6}.\frac{2}{6}=\frac{6}{6}=1\)\(\frac{1}{2}:\frac{1}{3}=\frac{1}{2}.\frac{3}{1}=\frac{3}{2}\)

Answer 6

+> 1/2 + 1/3 = 3/6 + 2/6 = 5/6

+>1/2 - 1/3 = 3/6 - 2/6 = 1/6

+>1/2 x 1/3 = 1/6

+>1/2 : 1/3 =

1/2 x 3/1 = 3/2 

hok tốt .
