[Lynk]

a, X : 1/3 = 4/5 

b, X : 3/5 = 7/9 

c, X x 3/4 = 7/6 

d, 4/8 x X = 9/7 

Answer 1

[Lihnn_xj]

\(a,x=\dfrac{4}{5}\times\dfrac{1}{3}=\dfrac{4}{15}\)

\(b,x=\dfrac{7}{9}\times\dfrac{3}{5}=\dfrac{7}{15}\)

\(c,x=\dfrac{7}{6}\times\dfrac{4}{3}=\dfrac{14}{9}\\ d,x=\dfrac{9}{7}\times\dfrac{8}{4}=\dfrac{18}{7}\)

Answer 2

[Nguyễn Ngọc Diệp]

X=4/15

X=7/15

X=14/9
