Ta có:A=\(\frac{7.9.\left(1+2.3+3.4\right)}{21.27.\left(1+2.3+3.4\right)}=\frac{7.9}{21.27}=\frac{1}{9}\)
Vậy A=\(\frac{1}{9}\)

Ta có:A=\(\frac{7.9.\left(1+2.3+3.4\right)}{21.27.\left(1+2.3+3.4\right)}=\frac{7.9}{21.27}=\frac{1}{9}\)
Vậy A=\(\frac{1}{9}\)
Rút gọn: A = 7.9 + 14.27 + 21.36 / 21.27 + 42.81 + 63.108
1)Rút gọn: A=7.9+14.27-21.36 / 21.27+42.81+63.108
Rút gọn phân số :
A = \(\frac{7.9+14.27+21.36}{21.27+42.81+63.108}\)
rút gọn phân số \(\frac{7.9+14.27+21.36}{21.27+42.81+63.108}\)
Rút gọn phân số: \(\frac{7.9+14.27+21.36}{21.27+42.81+63.108}\)
Rút Gọn: 7.9+14.27+21.36
21.27+42.81+63.108
rút gon \(A=\frac{7.9+14.27+21.36}{21.27+42.81+63.108}\)
CẢM ƠN !
So sánh:\(M=\frac{7.9+14.27+21.36}{21.27+42.81+63.108}và M=\frac{37}{333}\)
rút gọn 7.9+14.27+11.36/21.27+42.81+63.108
