5/6=1/2+1/3

7/12=1/2+1/12

7/8=1/2+1/4+1/8

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

b)\(\frac{7}{12}=\frac{1}{2}+\frac{1}{12}=\frac{1}{3}+\frac{1}{4}\)

c)\(\frac{7}{8}=\frac{1}{8}+\frac{6}{8}\)

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

\(\frac{7}{12}=\frac{1}{3}+\frac{1}{4}\)

a)1/2+1/3

b)1/3+1/4

c)1/3+1/5

Đáp án:

 5/6=1/3+1/2

7/12=1/4+1/3

8/15=1/5+1/3

17/24=1/8+1/2+1/3

Trả lời:

 5/6=1/3+1/2

7/12=1/4+1/3

8/15=1/5+1/3

17/24=1/8+1/2+1/3

35/36= 1/36+3/36+4/36+6/36+9/36+12/36

ha ha gà quá

a, \(\dfrac{5}{6}=\dfrac{1}{2}+\dfrac{1}{3}\)

b, \(\dfrac{7}{8}=\dfrac{1}{2}+\dfrac{1}{4}+\dfrac{1}{8}\)

c, \(\dfrac{6}{5}=\dfrac{1}{1}+\dfrac{1}{5}\)

d, \(\dfrac{8}{7}=\dfrac{1}{1}+\dfrac{1}{7}\)

\(a,\dfrac{5}{6}=\dfrac{1}{2}+\dfrac{1}{3}\\ b,\dfrac{7}{8}=\dfrac{1}{8}+\dfrac{1}{4}+\dfrac{1}{2}\\ c,\dfrac{6}{5}=\dfrac{1}{1}+\dfrac{1}{5}\\ d,\dfrac{8}{7}=\dfrac{1}{1}+\dfrac{1}{7}\)

Giải:

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

b) \(\dfrac{7}{8}=\dfrac{1}{2}+\dfrac{1}{4}+\dfrac{1}{8}\)

c) \(\dfrac{6}{5}=\dfrac{1}{1}+\dfrac{1}{5}\)

d) \(\dfrac{8}{7}=\dfrac{1}{1}+\dfrac{1}{7}\)

Hok tốt 

\(\dfrac{7}{8}=\dfrac{1}{2}+\dfrac{1}{4}+\dfrac{1}{8}\)

\(\dfrac{11}{12}=\dfrac{1}{2}+\dfrac{1}{4}+\dfrac{1}{6}\)

\(\dfrac{14}{24}=\dfrac{7}{12}=\dfrac{1}{6}+\dfrac{1}{3}+\dfrac{1}{12}\)
