Answer 1

[Oxford Đinh]

Ta có: \(\frac{3.125+3.125}{6.50+12.50}=\frac{125.\left(3+3\right)}{50.\left(6+12\right)}\)

           =\(\frac{125.6}{50.18}=\frac{25.5.6}{25.2.6.3}=\frac{5}{2.3}\)

          =\(\frac{5}{6}\)

Answer 2

[Lạnh Lùng Không Nói Ra Tên]

Hatsune Miku

Ta có\(\frac{3\times125+3\times125}{6\times50+12\times50}=\frac{125\times\left(3+3\right)}{50\times\left(6+12\right)}\)

\(=\frac{125\times6}{50\times18}=\frac{25\times5\times6}{25\times2\times6\times3}=\frac{5}{2\times3}\)

\(=\frac{5}{6}\)
