Explicație:
1. md mapa ms c
a. 20g 180g 200g 10 %
b. 15g 185g 200g 7,5%
c. 245g 105g 350g 70%
d. 30g 170g 200g 15%
e. 300g 700g 1000g 30%
calcule :
a. ms= md +mapa= 20 +180=200g
c= 20.100 : 200=10%
b. mapa= 200 -15= 185g
c=15.100 : 200= 7,5%
c. md= 350.70 :100=245g
mapa= 350-245= 105g
d. md= ms-mapa= 200 - 170=30g
c=30.100 : 200=15%
e. 30= md.100 : md + 700
30 ( md+700) = 100md
30md + 21000=100md
100md -30md= 21000
70md=21000
md=21000: 70= 300g
ms=md+mapa
ms= 300 + 700=1000g
