M = 4/31.7 + 6/7.41+ 9/10.41 + 7/10.57
A=4/7.31+6/7.41+9/10.41+7/10.57+13/57.14
B=4/31.7+6/7.41+9/10.41+7/10.57
A=4/19.31+6/7.41 +9/10.41+ 7/10.57
Tính A
Bài 5: Thực hiện phép tính \(\dfrac{4}{7.31}+\dfrac{6}{7.41}+\dfrac{9}{10.41}+\dfrac{7}{10.57}\)
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 nhanh A/B
\(\frac{4}{7.31}+\frac{6}{7.41}+\frac{9}{10.41}+\frac{7}{10.57}=?\)
1) cho 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
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
