Răspuns :
444-144=300 (e suma a trei jumatati)
300:3=100 (este o jumatate)
100.2=200 (are Maria)
200+144=344 (are Victor)
300:3=100 (este o jumatate)
100.2=200 (are Maria)
200+144=344 (are Victor)
a - nr timbrelor Mariei
b- nr timbrelor lui Victor
b = a + 144
b + a/2 = 444
a+ 144 + a/2 = 444
a+0,5a = 444- 144
1,5a = 300
a = 300: 1,5
a = 200
Maria are 200 timbre
Victor are 200+ 144 = 344 timbre
b- nr timbrelor lui Victor
b = a + 144
b + a/2 = 444
a+ 144 + a/2 = 444
a+0,5a = 444- 144
1,5a = 300
a = 300: 1,5
a = 200
Maria are 200 timbre
Victor are 200+ 144 = 344 timbre
