[ước mơ]

tính giá trị biểu thức : ( 9/10+1/10:4/5) x ( 3/15-2/15*4/3*9/8)

Answer 1

[Phạm Quang Long]

\(\left(\frac{9}{10}+\frac{1}{10}\div\frac{4}{5}\right)\times\left(\frac{3}{15}-\frac{2}{15}\times\frac{4}{3}\times\frac{9}{8}\right)\)

\(=\left(1\div\frac{4}{5}\right)\times\left(\frac{3}{15}-\frac{1}{5}\right)\)

\(=\frac{5}{4}\times0\)

\(=0\)
