Divide each charge with the smallest charge number:

$\mathbf{A}\mathbf{=}\frac{\overline{)\mathbf{-}}\mathbf{4}\mathbf{.}\mathbf{5}\mathbf{×}{\mathbf{10}}^{\mathbf{-}\mathbf{9}}}{\overline{)\mathbf{-}}\mathbf{4}\mathbf{.}\mathbf{5}\mathbf{×}{\mathbf{10}}^{\mathbf{-}\mathbf{9}}}\mathbf{=}\mathbf{1}$

$\mathbf{B}\mathbf{=}\frac{\overline{)\mathbf{-}}\mathbf{9}\mathbf{.}\mathbf{0}\mathbf{×}{\mathbf{10}}^{\mathbf{-}\mathbf{9}}}{\overline{)\mathbf{-}}\mathbf{4}\mathbf{.}\mathbf{5}\mathbf{×}{\mathbf{10}}^{\mathbf{-}\mathbf{9}}}\mathbf{=}\mathbf{2}$

$\mathbf{C}\mathbf{=}\frac{\overline{)\mathbf{-}}\mathbf{6}\mathbf{.}\mathbf{0}\mathbf{×}{\mathbf{10}}^{\mathbf{-}\mathbf{9}}}{\overline{)\mathbf{-}}\mathbf{4}\mathbf{.}\mathbf{5}\mathbf{×}{\mathbf{10}}^{\mathbf{-}\mathbf{9}}}\mathbf{=}\mathbf{1}\mathbf{.}\mathbf{33}$

$\mathbf{D}\mathbf{=}\frac{\overline{)\mathbf{-}}\mathbf{12}\mathbf{.}\mathbf{0}\mathbf{×}{\mathbf{10}}^{\mathbf{-}\mathbf{9}}}{\overline{)\mathbf{-}}\mathbf{4}\mathbf{.}\mathbf{5}\mathbf{×}{\mathbf{10}}^{\mathbf{-}\mathbf{9}}}\mathbf{=}\mathbf{2}\mathbf{.}\mathbf{66}$

Multiply each to get the whole number ratio for each:

A = 1 × 3 = 3

B = 2 × 3 = 6

C = 1.33 × 3 = 4

D = 2.66 × 3 = 8

Divide the charges with the ratios obtained
