Explicație pas cu pas:
8 c.................... 5 p ......................... 3400 g
4 c .................... 9 p......................... 3000 g/x2
8 c.................... 5 p ......................... 3400 g
8c ................... 18 p......................... 6000 g (se scad si se obtine)
/ ...................... 13 p......................... 2600 g
13p=2600 g
1 p=2600:13=200 g nuca
1p =200 g nuca
4c ................... 200x9p ................... 3000g
4c .....................1800 ......................3000g
4c=3000-1800=1200
1c=1200:4 = 300 g nuca
1c=300 g nuca
