tìm x
a x/5 =8/10
b 9/x=90/100
c 17+x/35 =5/7
d x:5/27=2/9
Tìm x
a) x + 2/5 = 1/2
b) x + 3/7 = 2/5 + 3/10
c) 19 - x = 8/5 - 3/4
1.Tìm x
a) 9/2 - x = 3/7 b) x : 5/7 = 7/5 c) x x 3/8 = 11/3
Tìm X
a)8/X+1/5=2/5+1/3
B)(X-3/5):1/5=5/8

Tìm x
a, \(\dfrac{5}{8}\) \(-\) \(x\) \(=\) \(\dfrac{4}{7}\) x\(\dfrac{1}{4}\)
b, \(x:\) \(\dfrac{4}{5}\) \(=\) \(\dfrac{3}{4}\) \(+\) \(\dfrac{1}{6}\)
Tìm x
a) x nhân 11/8 = 33/20 b) 5 : x = 4/7
Ai xong trước thì tui mới kich đúng
Đặt tính rồi tính:
1232 x 21
tìm x
a.9/25-12/25:x=1/5
b.8/17*x+2/9=10/27
tìm x
a.9/25-12/25:x=1/5
b.8/17*x+2/9=10/27
