Question

Tìm x : a, x × 1\2 = 1\3 b, x : 4\5 = 5\2 c, 2\9 : x = 2\3

Answer 1

a,x x 1/2 = 1/3 

b,x : 4/5 = 5/2

2/9 : x = 2/3 

Bài toán này :

X x 1/2 = 1/3

X = 1/3 : 1/2 

X = 2/3

X : 4/5 = 5/2

X  = 5/2 x 4/5

X = 1/2

2/9 : X = 2/3

X = 2 / 9 : 2/ 3

X = 3 

Answer 2

x=3

Answer 3

a) \(x.\frac{1}{2}=\frac{1}{3}\)

\(x=\frac{1}{3}:\frac{1}{2}\)

\(x=\frac{2}{3}\)

b) \(x:\frac{4}{5}=\frac{5}{2}\)

\(x=\frac{5}{2}.\frac{4}{5}\)

\(x=2\)

c) \(\frac{2}{9}:x=\frac{2}{3}\)

\(x=\frac{2}{9}:\frac{2}{3}\)

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

Answer 4

-6/7+4/5+-2/9+-1/2+1/5
