Question

\(4\frac{3}{4}+\left(-0,37\right)+\left(-1.28\right)+\left(-2,5\right)+3\frac{1}{2}\)

(các bn giải giúp mình với)

Answer 1

\(=\frac{19}{4}+\left(-\frac{37}{100}\right)+\left(-\frac{32}{25}\right)+\left(-\frac{5}{2}\right)+\frac{7}{2}\)

\(=\frac{219}{50}+\left(-\frac{32}{25}\right)+\left(-\frac{5}{2}\right)+\frac{7}{2}\)

\(=\frac{31}{10}+\left(-\frac{5}{2}\right)+\frac{7}{2}\)

\(=\frac{31}{10}+\left(-\frac{25}{10}\right)+\frac{35}{10}\)

\(=\frac{41}{10}\)

Answer 2

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

\(=\frac{19}{4}-\frac{37}{100}-\frac{128}{100}-\frac{25}{10}+\frac{7}{2}\)

\(=\frac{475}{100}-\frac{37}{100}-\frac{128}{100}-\frac{250}{100}+\frac{350}{100}\)

\(=\frac{410}{100}=4,1\)
