x - 3/11 = 4/5
x = 4/5 + 3/11
x = 59/55
x - 3/11 = 4/5
x = 4/5 + 3/11
x= 59/4
tk mình nhé
x - 3/11 = 4/5
x = 4/5 + 3/11
x = 59/55
x - 3/11 = 4/5
x = 4/5 + 3/11
x = 59/55
x - 3/11 = 4/5
x = 4/5 + 3/11
x= 59/4
tk mình nhé
x - 3/11 = 4/5
x = 4/5 + 3/11
x = 59/55
dung hay sai
5/7 + 3/4 = 41/28 ........
3 + 2/5 = 1........
11/9 - 5/6 = 7/18.......
4 - 3/7 = 25/7.....
tim x
x + 4/11 =3/5
a 13/3 b 13/11 c 13/55 d 13/31
bai6: tim x: x:9/4+1/3=11/18 lam kieu gi
bang 5/8
cau6: tim x

giup minh
bang 5/8
bai 5 tim X
a)x+4/11*11/42=1/3 b)15/28*x=3/7 c)19-x*5/9=14
x-11/5=2/5:2/3

Ai nhanh to k
x x - 4/7 = 15/20
x x 2/7 -2/3 =1/2
x : 5/4 + 4/5 =2
2 tinh
4/3 x 7/8 x 5
8/9 x 6/5 x 2/3
4/7 : 5/7 x 10/11
8/13 : 7/13 : 4
BAI 1 TINN
a]5/11-[3/5-6/11] b] 5/7-[19/35-16/15]
bai 2 tim x
a]x+3/7=2/5+3/10 b]2/3-x=8/21 c]19/20-x=8/5-3/4 giai nhanh ho minh mai minh phai di hoc
Tim X la so tu nhiên biết : X < 11/3 cong 5/7
Tim x :
X - 3/2 = 11/4
