Bài 2:

\(\frac{13}{36}=\frac{1+5+7}{36}=\frac{1}{36}+\frac{5}{36}+\frac{7}{36}\)

\(\frac{31}{60}=\frac{1+23+7}{60}=\frac{1}{60}+\frac{23}{60}+\frac{7}{60}\)

Bài 1:

\(\frac{25}{27}=\frac{1+3+9+3+9}{27}=\frac{1}{27}+\frac19+\frac13+\frac19+\frac13\)

\(\frac{15}{16}=\frac{8+7}{16}=\frac12+\frac{7}{16}=\frac12+\frac{4+3}{16}=\frac12+\frac14+\frac{3}{16}\)

\(=\frac12+\frac14+\frac{2+1}{16}=\frac12+\frac14+\frac18+\frac{1}{16}\)

\(\frac{13}{36}=\frac{1+3+9}{36}=\frac{1}{36}+\frac{1}{12}+\frac{1}{4}\)\(\frac{13}{36}=\frac{1+3+9}{36}=\frac{1}{36}+\frac{1}{12}+\frac{1}{4}\)

13/36 = 1/9 + 1/4

1/9 và 1/4 nha

35/36= 1/2+ 1/4+ 1/9+ 1/12+ 1/36

mk cần gấp 

mk sẽ tick câu trả lời đúng

13/27 = 1/9 + 10/27

vh 875

vh 675 là gì vậy Dorabase

khiếp cái bn dorabase trả lời cái kiểu gì và này nọ

vh 675 là j ý

35/36=1/12+1/9+1/2+1/4+1/36

\(\frac{10}{27}=\frac{1}{27}+\frac{5}{27}+\frac{4}{27}\)

\(\frac{13}{12}=\frac{1}{12}+\frac{7}{12}+\frac{5}{12}\)

\(\frac{15}{8}=\frac{7}{8}+\frac{5}{8}+\frac{3}{8}\)

cám ơn mọi người

\(\dfrac{13}{35}=\dfrac{1}{7}+\dfrac{1}{5}+\dfrac{1}{35}\)

\(\dfrac{13}{35}=\dfrac{1}{5}+\dfrac{1}{7}+\dfrac{1}{35}\)

\(\dfrac{13}{35}\) = \(\dfrac{1+5+7}{35}\) = \(\dfrac{1}{35}\) + \(\dfrac{5}{35}\) + \(\dfrac{7}{35}\) = \(\dfrac{1}{35}\) + \(\dfrac{1}{7}\) + \(\dfrac{1}{5}\)

\(\frac{13}{16}=\frac{1}{2}+\frac{1}{4}+\frac{1}{16}\)
