Question

\(\frac{399x45+55x399}{1995x1996-1991x1995}\)

Answer 1

=\(\frac{399x\left(45+55\right)}{1995x\left(1996-1991\right)}\)

=\(\frac{399x100}{1995x5}\)

=\(\frac{399x4x5x5}{399x5x5}\)

=\(\frac{4}{1}\)

=\(4\)

Answer 2

= \(\frac{17955+21945}{3982020-3972045}\)

= \(\frac{39900}{9975}\)

= \(\frac{7980}{1995}\)

= \(\frac{1596}{399}\)

= \(\frac{532}{133}\)

Aswer : \(\frac{532}{133}\)
