11/3-2/3(2 2/5x1/4+0,2)
các bạn giúp mik với
Tìm X
x - 11/15 = 3+X/5 2/5x1/X + 1/X x 2 + 2/5 = 1/2
Cảm ơn
2/5x1/4:3/8
A=[3/10+4/5x1/2]:[1 và 8/9-1 và 1/3]
Tìm M:1/2 :(1/3:1/4:1/5x1/120)=2008
bài 1: tính
ví dụ: 25-2:(3/5-1/2)+(5/2+1/5x1/4)
=25-2:1/10+(5/2+1/20)
=25-20+51/20
=5+51/20=151/20
a, (3/10+4/5x1/2):(17/9-4/3:3) b, (6:3/5-7/6x3/14):(21/5x10/11+57/11)
c, 4x1/5+(1/5-1/7)x(1/2:1/7)
ai làm nhanh mình tik

tính
a . 12/5x4-4x7/5
b . 14/3-1 5/9x21/4
C . 2/6x3/7:4/3
d . 2 3/5:2 1/4+5/2
e . 3 2/5x1 4/7+12/35
chỗ nào mk cách nhiều thì đó là hỗn số nha
