Answer 1

Odpowiedź:

a) x=0.3636

100x=36.36

100x=36+x

99x=36

x=36/99=12/33

b) x=3,7272

100x=372.72

100x=372+x

99x=372

x=372/99=124/33

c) x=-6.2424

100x=-624.24

100x=-624+x

99x=-624

x=-624/99=-208/33

d) x=0.99

10x=9.9

10x=9+x

9x=9

x=9/9=1

e) x=41,799

100x=4179.9

100x=4179+x

99x=4179

x=4179/99=1393/33

f) x=2,15252

1000x=2152.52

1000x=2152+x

999x=2152

x=2152/999
