tìm x
a)x+2 1/6=3 1/3
b)x-2 3/7=3
c)x x 1 1/3=2 2/3
tìm y : 3 x y x ( 1/1 x 1/2 + 1/2 x 1/3 + 1/3 x 1/4 + 1/4 x 1/5 + 1/5 x 1/6 ) = 3/4
giúp em với gấp lắm
Tìm X
X:3\(\dfrac{1}{15}\)-\(\dfrac{3}{4}\)=2\(\dfrac{1}{4}\)
X nhân 3\(\dfrac{2}{3}\)-1\(\dfrac{2}{3}\)=2\(\dfrac{1}{3}\)
tìm x
câu 1: 10/3 *x -1/2 =1/10
câu 2 : 1 / 3 * x + 1/3 *x=1/8
câu 3 : [ 3 x -1 ] [ 1/2 x -2/5 ] = 0
Tìm x : biết 1 / 1 x 2 + 1 / 2 x 3 + 1 / 3 x 4 +……+ 1 / ( x – 1) . x = 15 / 16
Tìm x :
biết 1 / 1 x 2 + 1 / 2 x 3 + 1 / 3 x 4 +……+ 1 / ( x – 1) . x = 15 / 16
Bài 6: Tìm x, biết
a) \(\dfrac{3}{2}\) x \(\dfrac{4}{5}\) - X =\(\dfrac{2}{3}\)
b) X x 3\(\dfrac{1}{3}\) = 3\(\dfrac{1}{3}\) : 4\(\dfrac{1}{4}\)
c) 5\(\dfrac{2}{3}\) : x = 3\(\dfrac{2}{3}\) - 2\(\dfrac{1}{2}\)
Tìm x
10/3. 1/2 -(1/2. x- 1/3) + 1/5= 3/5: 1/2
Tìm x:
1/2.(x+2/3)+1/3.(x+3/4)+1/4.(x+4/5)=3
Tìm x
X - 1\(\dfrac{1}{2}\) = 2 \(\dfrac{3}{5}\)
1/3 + 12/5 : x = 3\(\dfrac{2}{3}\)
3384 : 94 : x = 9
