Answer 1

3c.............4p..........2.300 g  /x7

7c.............7p..........4.200 g / x3

21c...........28 p..........16.100 g

21c..........21 p............12.600g

28-21=7 p

16.100-12.600=3.500 g ( au 7 paini)

3.500:7=500g ( are o paine)

4x500=2.000g (au 4 paini)

2.300-2000= 300 g (au 3 covrigi)

300:3=100g (are un covrig)
