Calculeaza diferenta nr 824532 si 698845 apoi dubleaza rezultatul.
natita [175]

Răspuns:

693860

Explicație pas cu pas:

Diferența dintre: 824532 și 698845

824532 - 698845 = 125687

Dublând rezultatul, r:

2 * 125687 = 251374

Pentru a obține: 3 * 315078 = 945234

Numărul care trebuie adăugat la r, în altul pentru a obține 945234 este:

945234 - 251374 = 693860

Prin urmare, 693860 trebuie adăugat la 251374 pentru a obține (3 * 315078)
