Question

Determină termenul necunoscut din egalitățile:

a) 400 g + 330 dg + a = 4 kg
b) 60 q + 2 800 kg - c = 4t
c) 732 g +75 dg - b = 25 g
d) 100 kg - 1 000 g- d = 50 kg

Coroana la răspuns corect​

Answer 1

a) 400g+330dg+a=4kg

400g+33g+a=4000g

a=4000g-433g

a=3567g

a=3,567kg

b) 60q+2800kg-c=4t

60q+28q-c=40q

c=88q-40q

c=48q

c) 732g+75dg-b=25g

732g+7,5g-b=25g

b=724,5g-25g

b=699,5g

d) 100kg-1000g-d=50kg

100kg-1kg-d=50kg

d=99kg-50kg

d=49kg
