\(\frac{4}{7}+x=\frac{5}{7}\cdot\frac{1}{2}\)
\(\frac{4}{7}+x=\frac{5}{14}\)
\(x=\frac{5}{14}-\frac{4}{7}\)
\(x=\frac{5}{14}-\frac{8}{14}\)
\(x=-\frac{3}{14}\)
4/7+x=5/7.1/2
4/7+x=5/14
x=5/14-4/7
x=-3/14
tính nhanh 3/7x1/5+2/3x3/7-3/7x1/8 giúp mình với mình đang cần gấp
1/7x1/2:1/7= 1/7x1/2x....=....?
Tính nhanh
5/6x1/7-1/7x1/6
8/15:4/5x3/2
4/3x1/7+4/7x1/11+4/11x1/15+4/15x1/19=?
1/7x1/7-3/7x1/7-3/8+1/3 tính kiểu gì cũng được
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 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 là số tự nhiên :
2/7 x X/3 x 4/5 = 2/3 x 4/5 x 6/7
Tìm X:
a).X:1/2=3/4
b).X-1/2=4/5
c).X+2/3=7/5
d).X x 5/4=2/7
e).7/3-x=4/7
f).5/9:x=4/13
g).1/2+x=3/4
h).1/2-x=3/4
i).2/3x X =7/5
k).X:5/4=2/7
l).7/3-x=4/7x14/8
