Question

[Nguyễn Bảo Ngân]

Tính bằng cách thuận tiện nhất :

47 / 53  :  17 / 52 -  47 / 53  x  35 / 17

Answer 1

[# APTX _ 4869 _ : ( $>$ )]

\(\frac{47}{53}\div\frac{17}{52}-\frac{47}{53}\times\frac{35}{17}\)

\(=\frac{47}{53}\times\frac{52}{17}-\frac{47}{53}\times\frac{35}{17}\)

\(=\frac{47}{53}\times(\frac{52}{17}-\frac{35}{17)}\)

\(=\frac{47}{53}\times\frac{17}{17}=\frac{47}{53}\times1=\frac{47}{53}\)
