Question

[Trần Minh Hải]

Tính bằng cách thuận tiện nhất 17/25 x 13/19 + 17/25 x 6/19

Answer 1

[𝑷𝒉𝒖𝒐𝒏𝒈 𝑨𝒏𝒉]

\(\frac{17}{25}\times\frac{13}{19}+\frac{17}{25}\times\frac{6}{19}\)

\(=\frac{17}{25}\times\left(\frac{13}{19}+\frac{6}{19}\right)\)

\(=\frac{17}{25}\times\frac{19}{19}\)

\(=\frac{17}{25}\times1\)

\(=\frac{17}{25}\)

_HT_
