\(4\frac{3}{4}+\left(-0,37\right)+\frac{1}{8}+\left(-1,28\right)+\left(-2,5\right)+3\frac{1}{12}\)

\(=4,75-0,37+0,125-1,28-2,5+\frac{37}{12}\)

\(=0,725+\frac{37}{12}\)

\(=\frac{457}{120}\)

\(\left(4\frac{3}{4}+\frac{1}{8}+3\frac{1}{12}\right)-\left(0,37+1,28+2,25\right)\)

\(=7\frac{23}{24}-4,15\)

\(=7\frac{23}{24}-4\frac{3}{20}\)

\(=\frac{19}{4}+\left(-0.37\right)+\frac{1}{8}+\left(-1.28\right)+\left(-2.5\right)+\frac{37}{12}\)\(\frac{37}{12}\)

\(=\left(\frac{19}{4}+\frac{1}{8}+\frac{37}{12}\right)+\left(\left(-0.37\right)+\left(-1.28\right)+\left(-2.5\right)\right)\)

\(=\frac{191}{24}+\left(-\frac{83}{20}\right)\)

\(=\frac{457}{120}\)

tu giai di ko biet nha!!!!

= 19/4 - 0,37 + 1/8 -  1,28 - 2,5 + 37/12

= 19/4 - 37/100 + 1/8 - 32/25 - 5/2 + 37/12 

= 219/50 + (-231/200) - 67/12

= 129/40 - 67/12

=(-283/120)

bạn k cho mình đi làm ơn đó 

\(4\frac{3}{4}-0,37+\frac{1}{8}-1,28-2,5+3\frac{1}{12}\)

\(=\frac{19}{4}-\frac{37}{100}+\frac{1}{8}-\frac{32}{25}-\frac{5}{2}+\frac{37}{12}\)

\(=\frac{4750}{1000}-\frac{370}{1000}+\frac{125}{1000}-\frac{1280}{1000}-\frac{2500}{1000}+\frac{37}{12}\)

\(=\frac{4750-370+125-1280-2500}{1000}+\frac{37}{12}\)

\(=\frac{29}{40}+\frac{37}{12}=\frac{87}{120}+\frac{370}{120}=\frac{457}{120}=3\frac{97}{120}\)

--Good luck--

\(4\frac{3}{4}-0,37+\frac{1}{8}-1,28-2,5+3\frac{1}{12}\)

= \(\frac{19}{4}-\frac{37}{100}+\frac{1}{8}-\frac{32}{25}-\frac{5}{2}+\frac{37}{12}\)

= \(\frac{4750}{1000}-\frac{370}{1000}+\frac{125}{1000}-\frac{1280}{1000}-\frac{1500}{1000}+\frac{37}{12}\)

= \(\frac{4750-370+125-1280-2500}{1000}+\frac{37}{12}\)

=\(\frac{29}{40}+\frac{37}{12}=\frac{87}{120}+\frac{370}{120}=3\frac{97}{120}\)

Good luck

=19/4-37/100+1/8-32/25-5/2+37/12

=(38/8+1/8-20/8)-(37/100+128/100)+37/12

=19/8-155/100+37/12

=469/120

tính hợp lí nha

Bài 1:

0,5\(x\) - \(\dfrac{2}{3}\)\(x\) = \(\dfrac{7}{12}\)  

\(\dfrac{1}{2}\)\(x\) - \(\dfrac{2}{3}x\)  = \(\dfrac{7}{12}\)

(\(\dfrac{1}{2}-\dfrac{2}{3}\))\(x\) = \(\dfrac{7}{12}\)

- \(\dfrac{1}{6}\)\(x\)         = \(\dfrac{7}{12}\)

     \(x\)         = \(\dfrac{7}{12}\) : (- \(\dfrac{1}{6}\))

     \(x\)        = - \(\dfrac{7}{2}\)

Vậy \(x\) = - \(\dfrac{7}{2}\)
