The moisture and acid content of whole and low-fat milk WAS/WERE 10% and 20% and 50% and 80%, respectively.<br/><br/>Ok...WAS or WERE?<br/><br/>CONTENT is uncountable noun in this case. But the way the sentence reads makes me want to use WERE (otherwise, it makes no sense)...<br/><br/>What's the correct answer here?<br/><br/>Thanks.
