\(\frac{3}{5}-\frac{6}{8}:\frac{3}{5}\)
=>\(\left(1-\frac{6}{8}\right):\frac{3}{5}\)
=>\(\frac{1}{4}:\frac{3}{5}\)
=>\(\frac{1}{4}\times\frac{5}{3}\)
=>\(\frac{5}{12}\)
\(\frac{3}{5}-\frac{6}{8}:\frac{3}{5}\)
\(=\frac{3}{5}-\frac{6}{8}.\frac{5}{3}\)
\(=\frac{3}{5}-\frac{10}{8}\)
\(=\frac{3}{5}-\frac{5}{4}\)
\(=\frac{12}{20}-\frac{25}{20}\)
\(=\frac{-13}{20}\)
Nhớ k cho m nha
3/5 - 6/8 : 3/5
= 3/5 - ( 6/8 . 5/3 )
=3/5 - 5/4
= 12/20 - 25/20
= -13/20
