Question

3 phần 5 + 4 phần 9 chia x = 2 phần 3

Answer 1

\(\dfrac{3}{5}\) + \(\dfrac{4}{9}\): \(x\) = \(\dfrac{2}{3}\)

\(\dfrac{4}{9}:x=\dfrac{3}{5}-\dfrac{2}{3}\)

\(\dfrac{4}{9}:x=\dfrac{-1}{15}\)

\(x=\dfrac{4}{9}:\dfrac{-1}{15}\)

\(x=\dfrac{-20}{3}\)

Answer 2

3/5+4/9:x = 2/3

4/9:x = 2/3 - 3/5

4/9:x = 1/15

x = 4/9:1/15

x = 20/3

Vậy x = 20/3
