You have to take the index values and convert everything to dollars in both periods using the relevant exchange rates. The % change will give you 10.417 and -2.64.

I had to lay out everything in a spreadsheet, otherwise it's easy to get lost.

UK Beg $ Value: 1090/.65 = 1676.923077
UK End $ Value: 1148/.62 = 1851.612903

Change = (1851.612903/1676.923077)-1 = 0.104172832

France Beg $ Value: 950/1.1 = 863.6363636
France End $ Value: 1009/1.2 = 840.8333333

Change = (840.8333333/863.6363636)-1 = -0.026403509
