Question

Ioana are in curte 58 de pasari. Ea are cu 4 rate mai mult decat gaste si cu 2 mai putine decat gaini. Cate pasari de fiecare fel are Ioana?​

Answer 1

Explicație pas cu pas:

nr pasari = 58

rate = gaste + 4 => gaste=rate-4

rate = gaini - 2 => gaini = rate + 2

=> rate + rate-4 + rate+2= 58

3rate= 58+2

rate = 20

gaini= 22

gaste = 16
