: 0.2. Cindezela 
: 1┘5, obhalwe emugqeni owodwa nophawu oluncane lwekhona phakathi kuka-1 no-5. Manje u-1 susa u-4 phezu kuka-5: thayipha 1, ucindezele 
, uthayiphe 4, ucindezele 
, uthayiphe 5, : 1┘5. Cindezela uthole 0.2. Bese ubuyela esikrinini semvelo: cindezela , , 
, futhi. Lokho kungukuphela kweNgxenye 2. ENgxenyeni 3, sibala ngezingxenyenamba, amaphesenti nokunye.
