*What are the rules for using “and” in large numbers?*

“And” comes between hundreds and tens, so not in the same position as commas.

*What are the rules for using commas in large numbers?*

Commas go after every group of three numbers and are how we show the transition from thousand to million, million to billion, etc.

*What are the rules for pronouncing numbers after a decimal point?*

Numbers after decimal points are pronounced one by one, so “point one hundred and twelve” would be wrong (or at least rare), it is “point one one two”.
