=About 4.4 $\times$ $10^{-2}$ deer per acre

You have $\frac{3.16*10^3}{7.228* 10^4}$.Simplify: $\frac{3.16*10^3}{7.228* 10^4}$ -subtract the exponents- $10^{3-4}$=$10^{-1}$ $\frac{3.16}{7.228}$ $\times$ $10^{-2}$ -divide the terms- 0.44 $\times$ $10^{-1}$ =About 4.4 $\times$ $10^{-2}$ deer per acre
