Câu 1 .Tính nhanh :
a ) 7/19 × 8/23 + 7/19 × 15/23 + 1và7/19
b) 75/100 + 18/21 + 49/32 + 1/4 + 3/21 - 17/32
c)8/9 × 15/16 × 24/25 × 35/36 × 48/49 × 63/64
Hộ mình với ạ , mình đang cần gấp. Bạn nào làm đúng mình tick cho
1 × 2 + 2 × 3 +3 × 4 + 4 × 5 + 5 × 6 + 6 × 7 + 7 × 8 + 8 × 9 + 9 × 10 + 10 × 11 +11 ×12 + 12 ×13 + 13×14 + 14×15 + 15×16 + 16×17 +17×18 + 18×19 + 19×20 + 20×21 + 21×22 + 22×23 + 23×24 + 24×25 + 25×26
A = -3/13 – 7/17 + -5/19 + 10/13 + 24/17 – 14/19
b) B = 1,25 . 7/19 + 5/4 . 15/19 – 1.1/4 : 19/3
