Question

tính giá trị biểu thức :

\(A=\dfrac{1717}{1919}x\dfrac{303}{1818}+\dfrac{1717}{1919}x\dfrac{1515}{1818}\)

Answer 1

\(A=\dfrac{1717}{1919}\left(\dfrac{303}{1818}+\dfrac{1515}{1818}\right)\\ =\dfrac{1717}{1919}.\dfrac{1818}{1818}\\ =\dfrac{1717}{1919}.1=\dfrac{1717}{1919}\)

Answer 2

\(A=\dfrac{1717}{1919}.\left(\dfrac{303}{1818}+\dfrac{1515}{1818}\right)\)

\(A=\dfrac{1717}{1919}.1\)

\(A=\dfrac{1717}{1919}\)
