Question

Cần gấp

 

Answer 1

a: \(x=\dfrac{1}{15}:\dfrac{5}{8}=\dfrac{1}{15}\cdot\dfrac{8}{5}=\dfrac{8}{75}\)

b: =>x+17/22=6

=>x=6-17/22=115/22

c: \(\Leftrightarrow x:\dfrac{6}{5}=5-\dfrac{2}{3}=\dfrac{13}{3}\)

hay x=78/15=26/5

Answer 2

a, \(x=\dfrac{1}{15}:\dfrac{5}{8}=\dfrac{8}{75}\)

b, \(\dfrac{17}{22}+x=6\Leftrightarrow x=6-\dfrac{17}{22}=\dfrac{115}{22}\)

c, \(x:\dfrac{18}{15}=5-\dfrac{2}{3}=\dfrac{13}{3}\Leftrightarrow x=\dfrac{13}{3}.\dfrac{18}{15}=\dfrac{26}{5}\)
