Question

Tim phan so a/b: 

5/6-a/b=1/2+1/4

ghu them loi giai?

Answer 1

Ta có : \(\frac{5}{6}-\frac{a}{b}=\frac{1}{2}+\frac{1}{4}\)

=> \(\frac{5}{6}-\frac{a}{b}=\frac{3}{4}\)

=> \(\frac{a}{b}=\frac{5}{6}-\frac{3}{4}\)

=> \(\frac{a}{b}=\frac{1}{12}\)

Answer 2

5/6-a/b=1/2+1/4

5/6-a/b=3/4

a/b = 5/6-3/4

a/b = 1/12

=> a = 1; b = 12

Answer 3

5/6 - a/b = 1/2 + 1/4

5/6 - a/b = 3/4

a/b = 5/6 - 3/4

a/b = 1/12 

Answer 4

5/6-a/b=1/2+1/4

5/6-a/b=3/4

a/b = 5/6-3/4

a/b = 1/12

=> a = 1; b = 12

hoặc

Ta có : $\frac{5}{6}-\frac{a}{b}=\frac{1}{2}+\frac{1}{4}$56 −ab =12 +14 

=> $\frac{5}{6}-\frac{a}{b}=\frac{3}{4}$56 −ab =34 

=> $\frac{a}{b}=\frac{5}{6}-\frac{3}{4}$ab =56 −34 

=> $\frac{a}{b}=\frac{1}{12}$ab =112
