Answer 1

Răspuns:a 4/3

B 5/5=1

C113/12

D

Explicație pas cu pas:

Answer 2

a) 1/3 + 5/3 = (1+5)/3 = 6/3 = 2

b) 9/5 - 4/5 = (9-4)/5 = 5/5 = 1

c) 213/12 - 100/12 = (213-100)/12 = 113/12

d) 35/36 * 6/7 = (se simplifica 35 cu 7, sus ramane 5, iar jos la 7 ramane 1; 36 se simplifica cu 6, sus la 6 ramane 1, iar jos 6) = 5/6

e) 1024/81 * 512/27 = 524288/2187

Cred ca mai degraba era impartire decat inmultire.

Daca e impartire, rezolvarea este:

1024/81 : 512/27 = 1024/81 * 27/512 = 2/3

f) 2320/196 : 120/96 = 2320/196 * 96/120 = 580/49 * 4/5 = 464/49
