\(\frac{8}{9}:\frac{10}{6}:\frac{12}{25}:\frac{14}{18}=\frac{8.6.25.18}{9.10.12.14}=\frac{21600}{15120}=\frac{10}{7}\)
là 10/7 nha bạn 100% lun
duyệt mình nha
\(\frac{8}{9}:\frac{10}{6}:\frac{12}{25}:\frac{14}{18}=\frac{10}{7}\)
8/9:10/6:12/25:14/18
= 8/9x6/10x25/12x18/14
= 8x6x25x18/9x10x12x14
= 21600/15120=10/7
\(\frac{8}{9}:\frac{10}{6}:\frac{12}{25}:\frac{14}{18}\)
= \(\frac{8}{9}:\frac{5}{3}:\frac{12}{25}:\frac{7}{9}\)
=\(\frac{8}{9}x\frac{3}{5}x\frac{25}{12}x\frac{9}{7}\)
=\(\frac{8x3x25x9}{9x5x12x7}\)
=\(\frac{10}{7}\)
