Hi this is an equation for how many Sra3 sheets I need to make 12 cards, it works which is a good start, but is the correct way to write it?

var a = this.getField("participant_1_total_packs_of_12_cards").value; //
event.value = a * 12 / 3; //

With thanks

Rusty

Looks fine to me. You might want to round the answer. This will round to 2 decimal places:
event.value = util.printf("%02.2f", a * 12 / 3);

The 'util.printf()' method is one of Acrobat JavaScirpt's 'util' object for formatting various stings. the printf method can specify how to format numbers of different bases or character strings of numbers into a specified number format. There are also the printd method for date and time and the printx method for character patterns. More information is contained in the Acrobat JavaScirpt API Reference.
