a). $1.10\times10^{2}$ b). $2.0\times10^{-3}$ c). $3.27\times10^{2}$ d). $1.80\times10^{5}$

a). $\frac{12.1}{1.10\times10^{-1}}=11\times10^{1}=1.10\times10^{2}$ b). $\frac{14\times10^{15}}{0.70\times10^{19}}=20\times10^{-4}=2.0\times10^{-3}$ c). $14.1\times23.2=327.12=3.27\times10^{2}$ d). $\frac{975}{0.00541}=180221.81=1.80\times10^{5}$
