\(3\frac{1}{117}\)x \(4\frac{1}{119}\)- \(1\frac{116}{117}\)x \(5\frac{115}{119}\)- \(\frac{5}{119}\)
= \(\frac{1889}{13923}\)
Tính nhanh:
\(3\frac{1}{117},4\frac{1}{119}-1\frac{116}{117},5\frac{118}{119}-\frac{5}{119}\)
\(Tính:A＝3\frac{1}{117}\times\frac{1}{119}-\frac{4}{117}\times5\frac{118}{119}-\frac{5}{117\times119}＋\frac{8}{39}\)
tính: A= 3\(\frac{1}{117}.\frac{1}{119}-\frac{4}{117}.5\frac{118}{119}-\frac{5}{117.119}+\frac{8}{39}\)
rút gọn M=\(3\frac{1}{117}.\frac{1}{119}-\frac{4}{117}.5\frac{118}{119}-\frac{5}{117.119}\)
\(Tính:A＝3\frac{1}{117}\times\frac{1}{119}-\frac{4}{117}\times5\frac{118}{119}-\frac{5}{117\times119}＋\frac{8}{39}\)
Tính giá trị biểu thức:
\(N=3.\frac{1}{117}.\frac{1}{119}-\frac{4}{117}.5\frac{118}{119}-\frac{5}{117.119}+\frac{8}{39}\)
Tính giá trị biểu thức:
\(A=3\frac{1}{117}\cdot\frac{1}{119}-\frac{4}{117}\cdot5\frac{118}{119}-\frac{5}{117\cdot119}+\frac{8}{39}\)
1,Tính giá trị biểu thức
a, D=3\(\frac{1}{117}\)* 4\(\frac{1}{119}\)- 1\(\frac{116}{117}\)* 5\(\frac{118}{119}\)- \(\frac{5}{119}\)
b, E=2\(\frac{1}{232}\)* \(\frac{1}{361}\)- \(\frac{1}{116}\)* 3\(\frac{360}{361}\)- \(\frac{3}{232\cdot361}\)+ \(\frac{1}{29}\)
Các bn giúp mk vs ạ.
Tính
\(A=3.\frac{1}{117}.\frac{1}{119}-\frac{4}{117}.5.\frac{118}{117}-\frac{5}{117.119}+\frac{8}{39}\)
