Giải gấp với G= 8/19 x 5/11+7/11 x 8/19 – 8/11 x1/19 30/07/2021 Bởi Josie Giải gấp với G= 8/19 x 5/11+7/11 x 8/19 – 8/11 x1/19
Giai = 8/19 x (5/11+7/11)-8/11 x 1/19 = 8/19 x 12/11– 8/11 x 1/19 = 96/ 209 – 8/209 = 88/209 = 8/19 Bình luận
8/19 x 5/11+7/11 x 8/19 – 8/11 x 1/19 = 8/ 19 ( 5/11 + 7/11) – 8/11 x 1/19 = 8/19 × 12/11 – 8/11 x 1/19 = 96/ 209 – 8/209 = 88/209 = 8/19 Bình luận

= 8/19 x (5/11+7/11)-8/11 x 1/19
= 8/19 x 12/11– 8/11 x 1/19
= 96/ 209 – 8/209
= 88/209 = 8/19
8/19 x 5/11+7/11 x 8/19 – 8/11 x 1/19
= 8/ 19 ( 5/11 + 7/11) – 8/11 x 1/19
= 8/19 × 12/11 – 8/11 x 1/19
= 96/ 209 – 8/209
= 88/209 = 8/19
