B=7/19.31+5/19.43+3/23.43+11/23.57
Tính A : B
Cho 2 biểu thức:
A= 4/7.31 + 6/7.41 + 9/10.41 + 7/10.57
B= 7/19.31 + 5/19.43 + 3/23.43 + 11/23.57
Tính A/B
Tính \(A= {4\over 7.31} + {7\over 7.41} + {9\over 10.41} + {7\over 10.57}\)
Tìm tỉ số A/B biết
A=4/7.31+6/7.41+9/10.41+7/10.57 và B=7/19.31+5/7.43+3/23.43+11/23.57
