c1: ( $\frac{9}{11}$ ) x $\frac{3}{4}$ = $\frac{8}{77}$ x $\frac{3}{4}$ = $\frac{6}{77}$ c2: Ở ẢNH = $\frac{6}{77}$ Bình luận
C1 ( 9/11-5/7)x3/4 = (9/11×3/4)-(5/7×3/4) =(9×3)/(11×4)-(5×3)/(7×4) =27/44-15/28 =6/77 C2 ( 9/11-5/7)x3/4 =(63/77-55/77)x3/4 =8/77×3/4 =6/77 Cho mk xin vote+câu tl hn ạ Bình luận
