So do the Danish, however the Danish language only counts the 10s in base-20. The 100s, the 1000s, the decimals and so on are still in base-10. So what ends up happening is that the numbers 40-90 are simply numbers with weird names and a perfect mapping to base 10. I don’t know how French count, but perhaps it is similar. This does not appear to be the case with Inuit counting.
