They all have a single b, so b will be part of our multiple. What else? What's the least common multiple of 4, 5 and 10?

Good good good :) So each fraction needs a bottom of 20b.

\[\Large\rm \color{royalblue}{\frac{5}{5}}\left(\frac{a+2}{4b}\right)-\color{royalblue}{\frac{2}{2}}\left(\frac{a-1}{10b}\right)+\color{royalblue}{\frac{4}{4}}\left(\frac{a+3}{5b}\right)\]Do you see how this step will help us achieve that?
