Question

Tính : \(15\frac{3}{40}.\frac{594}{40}-\frac{3}{40}.\left(-14\right)+\frac{3}{40}.\frac{23}{20}\)

Answer 1

\(15\frac{3}{40}.\frac{594}{40}-\frac{3}{40}.\left(-14\right)+\frac{3}{40}.\frac{23}{20}\)

\(=201.\frac{3}{40}.\frac{594}{40}-\frac{3}{40}.\left(-14\right)+\frac{3}{40}.\frac{23}{20}\)

\(=\frac{3}{40}.\frac{11859}{40}-\frac{3}{40}.\left(-14\right)+\frac{3}{40}.\frac{23}{20}\)

\(=\frac{3}{40}.\left(\frac{11859}{40}-\left(-14\right)+\frac{23}{20}\right)\)

\(=\frac{3}{40}.\frac{2493}{8}\)

\(=\frac{7579}{320}\)

Answer 2

7579/320

Answer 3

=221.78625

Answer 4

\(=15\frac{3}{40}.\frac{594}{40}-\frac{3}{40}.\left(-14+\frac{23}{20}\right)\)

\(=15\frac{3}{40}.\frac{594}{40}-\frac{3}{40}.\frac{-257}{20}\)

\(=223,86375-\frac{-771}{800}\)

\(=224,8275\)

\(=225\)

Answer 5
