Answer 1

Resposta:

a) 3 * (2/7) = 6/7 = 0,85

b) (6/7) * 8 = 48/7 =  6,85

c) 5 * 3 * (1/5) = 15/5 = 3

d) (3/4) * (7/9) = 21/36 = 7/12 = 0.58

e) (1/3) * (27/15) = 27/45 = 9/15 = 0.6

f) (2/3) * (10/4) * (9/15) = 180/180 = 1

g) (5/4) * (8/15) * (1/2) = 40/120 = 1/3 = 0.33

h) (7/9) * (3/2) * 0 = 0

i) 2 * (1/5) * (35/33) = 70/165 = 14/33 = 0.42

j) 1 * (3/7) * (63/40) = 189/280 = 27/40 = 0.67
