Tính nhanh
3/4 - 0,25 - (7/3 + - 9/2) - 5/6
Giúp mình nha!!!
1/3x+0,25=5/7
11/12x+0,25=5/6
(-1/3)2+2/3x=1/4
(3x+2)3=-8/125
Mk đag cấn gấp,please
-2^3 . (3/4-0,25):(9/4-7/6)
(2)^3.(3/4-0,25):(9/4-7/6)
D = (-2)^3×(3/4-0,25)÷(9/4-7/6)
a) s=(-2/3+1)-(7/5-0,2)+(7/15-1+4/3)
b) s=0,25-9-(-3/4)-[-7/3+(-9/2)]-5/6
3/4-0,25-( 7/3+(-9/2) )-5/6
Giúp mik câu này mik đag cần gấp
Tính :
1)3/5 x1/7 +3/5 x6/7 -3/5
2)6/7 x4/9 + 6/7 x5/9 + 6/7
3) 9/13 x 7/12 + 9/13 x 5/12 - 9/13
4) 4/13 x5/12 +4/13 x 7/12 - 4/13
a) s =(-2/3+1)-(7/5-0,2)+(7/15-1+4/3)
b) s=0,25 -(-3/4)-[-7/3+(-9/2)]-5/6
