b=25/18-5/4:3/2+9/4x16/27

Answer 1

[Nguyễn Thị Thương Hoài]

B = \(\dfrac{25}{18}\) - \(\dfrac{5}{4}\) : \(\dfrac{3}{2}\) + \(\dfrac{9}{4}\) \(\times\) \(\dfrac{16}{27}\)

B =  \(\dfrac{25}{18}\) - \(\dfrac{5}{4}\) \(\times\) \(\dfrac{2}{3}\) + \(\dfrac{4}{3}\)

B = \(\dfrac{25}{18}\) - \(\dfrac{5}{6}\) + \(\dfrac{4}{3}\)

B = \(\dfrac{25}{18}\) - \(\dfrac{15}{18}\) + \(\dfrac{24}{18}\)

B = \(\dfrac{34}{18}\)

B = \(\dfrac{17}{9}\)
