Question

( 1975 / 1976 + 2010 / 2011 + 1963 / 1968 ) nhân ( 1 phần 3 - 1 phần 4 - 1 phần 12)

 

Answer 1

( 1975 / 1976 + 2010 / 2011 + 1963 / 1968 ) x ( 1/3 - 1/4 - 1/12)

= ( 1975/1976 + 2010/2011 + 1963/1968) x ( 4/12 - 3/12 - 1/12)

= ( 1975/1976 + 2010/2011 + 1963/1968) x 0

=                    0

Answer 2

\(\left(\dfrac{1975}{1976}+\dfrac{2010}{2011}+\dfrac{1963}{1968}\right)\cdot\left(\dfrac{1}{3}-\dfrac{1}{4}-\dfrac{1}{12}\right)\)

\(=\left(\dfrac{1975}{1976}+\dfrac{2010}{2011}+\dfrac{1963}{1968}\right)\cdot\left(\dfrac{1}{12}-\dfrac{1}{12}\right)\)

\(=\left(\dfrac{1975}{1976}+\dfrac{2010}{2011}+\dfrac{1963}{1968}\right)\cdot0\)

= 0
