Question

Fie (a+b+c):15=34. Afla suma celor trei numere daca adunam cate patru unitati fiecarui numar

Answer 1

a+b+c=15×34
a+b+c=510
a+4+b+4+c+4=510
a+b+c+12=510
a+b+c=498

Answer 2

(a+b+c):15=34.

(a+b+c)=34×15

(a+b+c) = 510

daca adunam cate 4 unitati fiecarui numar, atunci la suma lor initiala (=510) se va aduna 4 ×3 =12 unitati

510 + 12 = 522
