Second, here is one GGB applet in Croatian (not mine), http://apleti.normala.hr:8180/xwiki/bin/view/Razlomci/BrojevniPravac . You should put the red circle to the right position (see the given fraction). After taht, click the 'Povuci' check box (Eng. 'Drag') and then you will know if you put it to the right position. If so, you cached a fish. :-) Then click the 'Nova točka' ckeck box (Eng. 'New point') to get new fraction and solve new problem.
