Question

a, Sắp xếp các phân số sau theo thứ tự tăng dần :  2/3 : 19/12 : 5/4 : 5/5 : 1/6.      b,tìm x :    8/11 x X = 1/5

Answer 1

\(=>\dfrac{1}{6}< \dfrac{2}{3}< \dfrac{5}{5}< \dfrac{5}{4}< \dfrac{19}{12}\)

Answer 2

a,\(\dfrac{1}{6},\dfrac{2}{3},\dfrac{5}{5},\dfrac{5}{4},\dfrac{19}{12}\)

b,\(\dfrac{8}{11}\)\(x=\dfrac{1}{5}\)

\(x=\dfrac{1}{5}:\dfrac{8}{11}\)

\(x=\dfrac{11}{40}\)

 

Answer 3

\(\dfrac{8}{11}xX=\dfrac{1}{5}=>X=\dfrac{1}{5}:\dfrac{8}{11}=>X=\dfrac{11}{40}\)

Answer 4

a, \(\dfrac{1}{6};\dfrac{2}{3};\dfrac{5}{5};\dfrac{5}{4};\dfrac{19}{12}\)

b, \(\dfrac{8}{11}.x=\dfrac{1}{5}\)

      \(x=\dfrac{1}{5}:\dfrac{8}{11}\)

      \(x=\dfrac{1.11}{8.15}\)

      \(x=\dfrac{11}{40}\)

Answer 5

a) Các p/s theo thứ tự tăng dần là:

\(\dfrac{1}{6};\dfrac{2}{3};\dfrac{5}{5};\dfrac{5}{4};\dfrac{19}{12}\) 

b) \(\dfrac{8}{11}\times x=\dfrac{1}{5}\) 

              \(x=\dfrac{1}{5}:\dfrac{8}{11}\) 

              \(x=\dfrac{11}{40}\)
