Answer 2

Resposta:

Explicação passo-a-passo:

a) 24/9 + 18/9

= 24+18/9

= 42/9

= 14/3

b) 35/12 + 21/12

= 35+21/12

= 56/12

= 14/3

c) 88/25 + 19/25

= 88+19/25

= 107/25

d) 43/17 - 25/17

= 43-25/17

= 18/17

e) 25/18 - 17/18

= 25-17/18

= 8/18

= 4/9

f) 54/33 - 45/33

= 54-45/33

= 9/33

= 3/11
