Các bn ơi giúp mk với mk cần gấp
( -5/7 - 7/5 + 9/11 - 11/13 ) * ( 3-3/4) : ( 10/21 + 14/27 - 6/33 + 22/39) : ( 2-2/3)
G = ( -5/7 - 7/9 + 9/11 - 11/13 ) . ( 3 - 3/4 ) phần ( 10/21 + 14/27 - 6/11 + 22/39 ) : ( 2 - 2/3 )
cần gấp ! ( đấy là phân số )
1. Thực hiện phép tính
G=(-5/7-7/9+9/11-11/13).(3-3/4)
phần (10/21+14/27-6/11+22/39):(2-2/3)
Tính nhanh: \(\frac{-5}{11}+\frac{7}{22}-\frac{-4}{33}-\frac{5}{44}=38\frac{1}{22}-39\frac{7}{22}\)
A =2\1*2+4\2*4+6\4*7+8\7*11+8\7*11+10\11*16
+12\16*22
Tính A
(-5/7 - 7/9 + 9/11 - 11/13) : ( 3 - 3/4 )
