\(=\left(\frac{9}{4}+\frac{7}{4}\right).3,25\)
\(=4.3,25\)

1) 1/3 - 5/6 + 3/2 2) 2/13 - ( 15/13 +4 - 0,5 ) 3) -( 1/9 +7/5 - 3/11) + ( -2/5 + 17/9 - 8/11 ) 4) 5,75 - 3,25 +5 5/6
\(12\frac{3}{11}-\frac{6}{13}+3,25-5\frac{3}{11}-4\frac{7}{13}+\sqrt{1\frac{9}{16}}\)
Tìm x, biết : (3,25 - 2/5x ) : -7/4=-3
Giúp mình với, pleaseeeee
Tính theo cách đổi ra phân số á
(3\(\dfrac{1}{2}\) + 0,25 ) - ( \(\dfrac{1}{4}\) - 3,25 + \(\dfrac{1}{2}\))
Tìm x biết :
\(5.\left|\frac{3}{4}-\frac{2}{3}x\right|-3,25=-2\left\{\left(1.25\right)^2-2,5.0,25+\left(-0,25\right)^2\right\}\)
(x-1)×(x+3,25)=0
2*X+3,25 =X+5,32
5.x-3,25-2.x-4,75=16
2*x+3,25 =X+5,32
Tính:
(-2,5 . 0,375 . 0,4) - [0,125 . 3,25 . (-8)]
