Question

Tính giá trị của biểu thức.

a) 35 700 : 50 + 68 × 46                       b) \(\dfrac{16}{9}\times\left(6:\dfrac{32}{9}\right)-\dfrac{7}{5}\)

Answer 1

a) 35 700 : 50 + 68 x 46 = 714 + 3 128

                                        = 3 842

b) $\frac{{16}}{9} \times \left( {6:\frac{{32}}{9}} \right) - \frac{7}{5} = \frac{{16}}{9} \times \left( {6 \times \frac{9}{{32}}} \right) - \frac{7}{5} = \frac{{16}}{9} \times \frac{{27}}{{16}} - \frac{7}{5} = 3 - \frac{7}{5} = \frac{{15}}{5} - \frac{7}{5} = \frac{8}{5}$
