The number of chickens eaten by Americans in one year is $4.064\times {{10}^{9}}$.
Express 127 in scientific notation as follows: $127=1.27\times {{10}^{2}}$ So, chickens eaten by Americans in one year is: \begin{align} & 1.27\times {{10}^{2}}\times \left( 3.2\times {{10}^{7}} \right)=4.064\times \left( {{10}^{2+7}} \right) \\ & =4.064\times {{10}^{9}} \end{align} Hence, the number of chickens eaten by Americans in one year is $4.064\times {{10}^{9}}$.
