\(\frac{12}{35}:\frac{26}{15}=\frac{12}{35}.\frac{15}{26}=\frac{6}{7}.\frac{3}{13}=\frac{18}{91}\)
bai nay de thui de mk giai ho cho
nha
theo to:
\(\frac{12}{35}:\frac{26}{15}=\frac{18}{91}\)
\(\frac{12}{35}:\frac{26}{15}\)
\(=\frac{12}{35}.\frac{15}{26}\)
\(=\frac{12.15}{35.26}\)
\(=\frac{2.6.5.3}{7.5.2.13}\)
\(=\frac{6.3}{7.13}=\frac{18}{91}\)
\(\frac{12}{35}\): \(\frac{26}{15}\)
=\(\frac{12}{35}\). \(\frac{15}{26}\)
= \(\frac{180}{910}\)
= \(\frac{18}{91}\)
tk nhé
