Question

impartiti nr 60 in parti direct proportionale cu 2, 3 si 5

Answer 1

Răspuns:

{a,b,c}d.p.{2,3,5}

a/2=b/3=c/5=k

a=2k

b=3k

c=5k

2k+3k+5k=60

10k=60

k=60÷10

k=6

a=6×2=12

b=6×3=18

c=6×5=30

Answer 2

Răspuns:

Explicație pas cu pas:

a/2 = b/3 = c/5 = k

a = 2k

b = 3k

c = 5k

a + b + c = 60

2k + 3k + 5k = 60

10k = 60

k = 60 : 10 = 6

a= 12

b = 18

c = 30
