Decimal points and sound change of counters


I understand that when a series of numbers in Japanese includes a decimal
point each number is voiced individually with the decimal point pronounced as
てん as in the following example:

> 9.76 = きゅうてんななろく

However, if I'm reading a series of digits which includes a counter that has a
sound change in the final digit like if I wanted to say for example

> 5.6 minutes (5.6分）

how would I read this?

Would I pronounce it as ごてん **ろっぷん**? Or would I simply ignore the sound
change in 6 related to the counter word (in this case 分) and simply pronounce
it as ごてん **ろくふん**?




Even if you read ６分 as ろくふん, it's ok. But ろっぷん is easier to pronounce and much
more common. It's the same when it's used like 5.6分, which is usually
ごーてんろっぷん.
