Explanation:
(4.3 x 10^6)*(9.8 x 10^-4)=4.214x10^3
(2.9 x 10^7)*(1.6 x 10^-9)=4.64x10^-2
(4.7 x 10^3)*(8.6 x 10^-7)=4.042x10^-3
(3.8 x 10^-4)*(6.1 x 10^2)=2.318x10^-1
(4.042x10^-3)/(2.318x10^-1)=1.74x10^-2
(4.9 x 10^3)*(7.4 x 10^-6)=3.626x10^-2
(3.9 x 10^5)*(8.7 x 10^-3)=3.393x10^3
(3.7 x 10^-5)*(2.9 x 10^8)=1.073x10^4
(3.393x10^3)/(1.073x10^4)=3.16x10^-1
