Toán $\frac{8}{15}$ x $\frac{25}{28}$ $\frac{4}{6}$ x $\frac{11}{13}$ 16/11/2021 By Eva $\frac{8}{15}$ x $\frac{25}{28}$ $\frac{4}{6}$ x $\frac{11}{13}$
Đáp án: $\frac{8}{15}$ x $\frac{25}{28}$ = $\frac{2 ×2×2 }{3×5}$ ×$\frac{5×5}{2×2×7}$ = $\frac{10}{21}$ $\frac{4}{6}$ ×$\frac{11}{13}$ = $\frac{2}{3}$ × $\frac{11}{13}$ = $\frac{22}{39}$ Trả lời
$\text{Đáp án:}$ $\text{Ban tham khao nha}$ `8/15` × `25/28` = $\dfrac{200}{420}$ = `10/21` `4/6` × `11/13` = $\dfrac{44}{78}$ = `22/39` $\text{chuc ban hoc tot nha}$ ^^ Trả lời
