2/7 x x = 6/5
x= 6/5 : 2/7
x = 6/5 x 7/2
x = 21/5
\(\dfrac{2}{7}\times x=\dfrac{6}{5}\)
\(\Rightarrow x=\dfrac{6}{5}:\dfrac{2}{7}\)
\(\Rightarrow x=\dfrac{21}{5}\)
Tìm x biết :
x + 4/5 = 4/5 + ( 3/7 + 3/5 ) 5/7 + x/35 = 4/5
x < 3/4 + 2 2/3 + 1 < x < 5/6 + 4
x< 5/6 - 3/4 2/3 < x < 2 - 5/6
Tìm x:
X : 3/4=5/6
X-2/3=4/6
7/10 : X=7/2
5/8 : X=5
Tìm x :
3/7 x x = 1/3
x : 6/8 = 2/5
x - 2/3 = 5/6
x - 2/5 - 4/35 = 1/7
1.tìm x a)x : 2/5 = 3/7 b) 6/5 - x = 7/8
Tìm x :
X + 5/9 = 4/3 X - 4/9 = 1/2 6/13 + X = 7/6 13/5 - X = 5/6
Giúp mình ạ !
Tìm x là số tự nhiên :
2/7 x X/3 x 4/5 = 2/3 x 4/5 x 6/7
Tìm x
3/4:6/x:8/7=3/8:4/5:6/7
2/5:x/3:7/4=24/315
tìm x x:9/5=6/11
x:4=2/7
tìm x:
a) \(\dfrac{24}{35}\) - x = \(\dfrac{2}{7}\)
b) x - \(\dfrac{5}{6}\) = \(\dfrac{7}{8}\)
c) x - \(\dfrac{11}{5}\) = \(\dfrac{2}{5}\) : \(\dfrac{2}{3}\)
(giải chi tiết hộ mình)
