PROBA :

a) 22 x 25,6(81) = 22 x (25681-256)/990 = 25425/45 = 565

c) 33,125 x 24 = 795

d) 32,48 x 25 = 812

e) 27 x 32,(7) = 27 x (327-32)/9 = 3 x 295 = 885

f) 26 x 36,(230769) = 26 x (36230769-36)/999999 =

= 2 x 36230733/76923 = 2 x 471 = 942

g) 28,2 x 35 = 987

h) 36 x 25,69(4) = 36 x (25694-2569)/900 =

= 23125 : 25 = 925

b) 23 x 26,(2608695652173913043478) =

= 23 x (262608695652173913043478 -26) /9999999999999999999999 =

= 262608695652173913043452 / 434782608695652173913 = 604
