الدليل
Ukrainian Grade 3 (part 1) studies the quantities of a work situation: productivity (how many items are made in 1 hour), working time, and total output (how many items are made altogether).
Total output is a product: productivity · working time = total output. So working time is found by division (total output : productivity), and so is productivity (total output : working time).
We write the problem in a short table, or in the triangle scheme: total output at the top, productivity and time at the bottom, the sign "·" between them. The unknown is marked with a question mark.
