=1/2+2+5/3=25/6 tk mk nha mình  là bạn cậu nè

=\(\frac{5}{6}\)

k cho mk vs nhé

k cho mk vs nhé

13/4+23/6-4/2=39/12+46/12-24/12 

                    =85/12-24/12

                    =61/12

chúc bạn học giỏi

\(12\frac{4}{3}+\frac{2}{6}=\frac{41}{3}\)

\(12\frac{4}{3}+\frac{2}{6}=16+\frac{1}{3}=\frac{49}{3}\)

12 + 4/3 + 2/6 = 12 + 5/3 = 41/3

\(\frac{3}{12}+\frac{2}{4}-\frac{2}{12}\)

\(=\frac{3}{12}+\frac{6}{12}-\frac{2}{12}\)

\(=\frac{3+6-2}{12}\)

\(=\frac{7}{12}\)

\(\frac{3}{12}+\frac{2}{4}-\frac{2}{12}\)

\(=\frac{3}{12}+\frac{6}{12}-\frac{2}{12}\)

\(=\frac{9}{12}-\frac{2}{12}\)

\(=\frac{7}{12}\)

\(\frac{3}{12}+\frac{2}{4}-\frac{2}{12}\)

\(=\frac{3}{12}+\frac{6}{12}-\frac{2}{12}\)

\(=\frac{7}{12}\)

\(2\frac{1}{2}:\frac{3}{4}=\frac{5}{2}:\frac{3}{4}\)

= 5/2 x 4/3

=\(\frac{20}{6}\)

M.n tk giùm em vs ạ !! ^_^

\(2\frac{4}{3}+\frac{4}{12}=\frac{2.3+4}{3}+\frac{4}{12}=\frac{10}{3}+\frac{4}{12}=\frac{40}{12}+\frac{4}{12}=\frac{44}{12}=\frac{11}{3}\)

\(2\frac{4}{3}=\frac{10}{3}\)

\(\frac{10}{3}+\frac{4}{12}=\frac{120}{36}+\frac{12}{36}\)

\(=\frac{132}{36}=\frac{22}{6}=\frac{11}{3}\)

12 : \(\frac{6}{2}=\frac{12}{1}x\frac{6}{2}=\frac{72}{2}\)

đúng không nè bạn

mình nè

= 2x4/3x4 + 3x3/4x3 +3/12=8/12+9/12+3/12=8+9+3/12=20/12=5/3

dễ sợ thiệt

Mấy bạn dùng mấy cái này để xin đúng

=10080

tk mình.,mình kb rồi

=10080nhe

kb nha minh la nguyen van

2 x 2 x 3 x 4 x 5 x 6 x 7 = 10080

mk sẽ kb nhưng k cho mk nhé
