Ringer BS: Find by Practice (31) BS: Find by Practice 11 Oct 13

When I was a schoolboy in England in the 1950s, in arithmetic classes we would sometimes be asked, for example, to "find by practice the cost of 37 articles each costing 1.17s 3d"

I cannot now remember the technique of finding by practice. Can anyone help? (I don't actually need the technique now; I'm just bugged by not being able to remember it.)
