Question

giá trị của biểu thức \(\dfrac{3}{5}\) : \(\dfrac{1}{3}\)  \(\dfrac{1}{2}\) x \(\dfrac{2}{3}\)

Answer 1

\(\dfrac{3}{5}:\dfrac{1}{3}\)

\(=\dfrac{3}{5}.\dfrac{3}{1}\)

\(=\dfrac{3.3}{5.1}\)

\(=\dfrac{9}{5}\)

------------------------------------

\(\dfrac{1}{2}.\dfrac{2}{3}\)

\(=\dfrac{1.2}{2.3}\)

\(=\dfrac{1}{3}\)

Answer 2

`3/5: 1/3= 3/5 xx 3=(3xx3)/5= 9/5`

`1/2xx 2/3=(1xx2)/(2xx3)=2/6=1/3`
