[Nguyen van manh]

Viết 9 phân số lơn hơn5/7 va bé hơn5/6

a; X×1/5=1-2/3

b; x:3/4=(2/3+1/3):3/4

Answer 1

[Thi Phạm Khánh]

\(\frac{5}{6}>?>\frac{5}{7}=\frac{35}{42}>?>\frac{30}{42}=\frac{35}{42}>\frac{34}{42};\frac{34,5}{42};\frac{33}{42};\frac{33,5}{42};\frac{32}{42};\frac{32,5}{42};\frac{31}{42};\frac{31,5}{42};\) \(\frac{30,5}{42}\)

a) \(x.\frac{1}{5}=1-\frac{2}{3}\)

\(x.\frac{1}{5}=\frac{1}{3}\)

\(x=\frac{1}{3}.5=\frac{1}{15}\)

b) \(x:\frac{3}{4}=\left(\frac{2}{3}+\frac{1}{3}\right):\frac{3}{4}\)

\(x:\frac{3}{4}=1:\frac{3}{4}=\frac{4}{3}\)

\(x=\frac{4}{3}.\frac{3}{4}=1\)
