\(x=\dfrac{7}{3}:\dfrac{2}{3}\)
\(x=\dfrac{21}{6}\)
\(X\times\dfrac{2}{3}=\dfrac{7}{3}\)
\(X=\dfrac{7}{3}:\dfrac{2}{3}\)
\(X=\dfrac{7}{2}\)
1.Tìm x
a) 9/2 - x = 3/7 b) x : 5/7 = 7/5 c) x x 3/8 = 11/3
tìm X biết :
a.2/3 : 5/7 : x/9 = 2/7 : 3/5 :10/9
b.3/5 : 7/x : 3/4 = 12/105
c.x : 1/2 = 2/3 x 4/5 x 3/4 x 15/8
Tìm x:
X x 4/7 + 1/3 x x = 2/3
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
3. Tìm x
a. x : 17/2 = 3
b. 17/2 : x = 4/3
c. x - 2/7 = 1
d. 7/3 - x = 5/3
tìm x
9/7 x x + 5/7 x x = 2/3
Tìm x là số tự nhiên :
2/7 x X/3 x 4/5 = 2/3 x 4/5 x 6/7
Tìm x :
3/7 x x = 1/3
x : 6/8 = 2/5
x - 2/3 = 5/6
x - 2/5 - 4/35 = 1/7
Bài 1: Tính
a) 1/3 + 1/5 - 1/4 b) 7/8 - ( 1/4 + 2/5 ) c) 5/11 - ( 3/5 - 6/11 )
Bài 2: Tìm x
a) x + 2/5 = 1/2 b) x + 3/7 = 2/5 + 3/10 c) 19/20 - x = 8/5 - 3/4
Bài 3: Tìm số tự nhiên x, biết:
a ) 4/7 < x < 1/2 + 10/3 b) 3/10 + 8/5 < x < 2/5 + 5
Giúp mình nha ^^ Ai nhanh mình Tick !!!!!!!!!❤❤
