Tìm thương của phép chia A cho B
A=40/31.39 + 45/39.46 + 30/46.52 + 30/52.57
B=91/19.31 + 65/19.43 + 39/23.43 + 143/69.19
\(A=\frac{40}{31.39}+\frac{35}{39.16}+\frac{30}{23.92}+\frac{25}{29.64}\) ; \(B=\frac{91}{19.31}+\frac{65}{19.43}+\frac{39}{989}+\frac{143}{1311}\).
Tính tỉ số A/B
Cho A=\(\frac{40}{31.38}+\frac{35}{39.46}+\frac{30}{2392}+\frac{25}{2962}\) và B=\(\frac{91}{19.31}+\frac{65}{19.43}+\frac{39}{989}+\frac{143}{1311}\).Tìm \(\frac{A}{B}\)
Tính tổng:
E =\(\frac{40}{31.38}+\frac{35}{39.46}+\frac{30}{2392}+\frac{25}{2962}\)
F =\(\frac{91}{19.31}+\frac{65}{19.43}+\frac{39}{989}+\frac{143}{1311}\)
Tính tổng:
E =\(\frac{40}{31.38}+\frac{35}{39.46}+\frac{30}{2392}+\frac{25}{2962}\)
F =\(\frac{91}{19.31}+\frac{65}{19.43}+\frac{39}{989}+\frac{143}{1311}\)
Cho A= \(\frac{40}{31.38}\)+\(\frac{35}{39.45}\)+ \(\frac{30}{2392}\)+ \(\frac{25}{2962}\)
B= \(\frac{91}{19.31}\)+\(\frac{65}{19.43}\)+\(\frac{39}{989}\)+\(\frac{143}{1311}\)
Tính \(\frac{A}{B}\)
Tính B=\(\left(\frac{7}{19.31}+\frac{5}{19.43}+\frac{3}{23.43}+\frac{11}{23.57}\right):\left(\frac{1}{31}-\frac{1}{57}\right)\)
