Question

Viết phân số 10phần 27 thành tổng của hai số tối giản có mẫu số khác nha

 

Answer 1

10/27 = 2/9 + 4/27

Answer 2

\(\dfrac{10}{27}\) = \(\dfrac{3+7}{27}\) = \(\dfrac{3}{27}\) +  \(\dfrac{7}{27}\) = \(\dfrac{1}{9}\) + \(\dfrac{7}{27}\)

\(\dfrac{10}{27}\) = \(\dfrac{1}{9}\) + \(\dfrac{7}{27}\)

\(\dfrac{10}{27}\) = \(\dfrac{6+4}{27}\) = \(\dfrac{6}{27}\) + \(\dfrac{4}{27}\) = \(\dfrac{2}{9}\) + \(\dfrac{4}{27}\)

\(\dfrac{10}{27}\) = \(\dfrac{9+1}{27}\) = \(\dfrac{9}{27}\) + \(\dfrac{1}{27}\) = \(\dfrac{1}{3}\) + \(\dfrac{1}{27}\)

\(\dfrac{10}{27}\) = \(\dfrac{1}{3}\) + \(\dfrac{1}{27}\)
