tìm x
x+4/5=4/5+(3/7+3/5
5/7+x/35=4/5
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 - 4/5 = 3/7
x + 3/7 = 4/5
19/20 - x = 8/5 - 3/4
4/5 x X = 6/9 - 4/7
x : 7/9 = 6/8
2/3 - x/6 = 6/18
Tìm x
x - 4/5 = 3/7
x + 3/7 = 4/5
19/20 - x = 8/5 - 3/4
4/5 x X = 6/9 - 4/7
x : 7/9 = 6/8
2/3 - x/6 = 6/18
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 số tự nhiên x biết
a) 0 <x<1/4 + 4/5 b) 4/7 + 3/7 <x< 5/3 + 2/3
tìm số tự nhiên x biết
a) 0 <x<1/4 + 4/5 b) 4/7 + 3/7 <x< 5/3 + 2/3
Tìm x
3/4:6/x:8/7=3/8:4/5:6/7
2/5:x/3:7/4=24/315
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+ 4/5=4/5+ (3/7+3/5) b) 5/7+ x/35=4/5
