Ta có:

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

\(=4:4:3-0,37+1:8-1,28-2,5+3:1:12\)

\(=\frac{1}{3}-\frac{37}{100}+\frac{1}{8}-\frac{32}{25}-\frac{5}{2}+\frac{1}{4}\)

\(=\frac{200}{600}-\frac{222}{600}+\frac{75}{600}-\frac{768}{600}-\frac{1500}{600}+\frac{150}{600}\)

\(=\frac{200-222+75-768-1500+150}{600}\)

\(=-\frac{2065}{600}\)

\(=-\frac{413}{120}\)

tính nhanh mà

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

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

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

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

\(\frac{19}{4}-\frac{37}{100}+\frac{1}{8}-\frac{32}{25}-\frac{5}{2}+\frac{7}{2}=\left(\frac{19}{4}-\frac{37}{100}-\frac{32}{25}\right)+\left(\frac{7}{2}-\frac{5}{2}\right)+\frac{1}{8}=\frac{31}{10}+1+\frac{1}{8}=\frac{169}{40}\)

sai đề nha mọi người

\frac8/8\

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

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

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

\(=3\frac{97}{120}\)

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

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

\(=\dfrac{219}{50}+\dfrac{1}{8}+-\dfrac{32}{25}+-\dfrac{5}{2}+\dfrac{37}{12}\)

\(=\dfrac{901}{200}+-\dfrac{32}{25}+-\dfrac{5}{2}+\dfrac{37}{12}\)

\(=\dfrac{129}{40}+-\dfrac{5}{2}+\dfrac{37}{12}\)

\(=\dfrac{29}{40}+\dfrac{37}{12}\)

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