Tính giá trị biểu thức :

A=\(\frac{10,07x12+20,14x141-20,14x47}{1007:0,5}\)

Answer 1

[Đức Phạm]

\(A=\frac{10,07\times12+20,14\times141-20,14\times47}{1007\div0,5}\)

\(A=\frac{10,07\times12+10,07\times2\times141-10,07\times2\times47}{2014}\)

\(A=\frac{10,07\times\left(12+2\times141-2\times47\right)}{2014}\)

\(A=\frac{10,07\times200}{2014}\)

\(A=\frac{2014}{2014}=1\)
