I have a sentence with amount definded in precentage. Should it look like this:
a) "The 85% of our products were going to EU."
b) "The 85% of our products was going to EU."
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
If the product were uncountable, we'd have;
85% of our oil was going to the EU.
