Hi
annamonikacommenting on paragraph:
Quantifying phrases (such as a number ef and a percentage ef) often function as subject modifiers in
what could appear to be a subject position. In such cases, they are treated similarly to numbers. ''A
large proportion of the trees are flowering" is essentially like "Three of the trees are flowering." In other
cases, similar phrases function as subjects. Consider, for example, the following correct phrases: "a small
percentage of our profits is reinvested" and "a small percentage of our employees oppose the new plan."
a number of ---> always plural because it can only be used with countable subjects. (note:
the number of --> singular)
a percentage of ---> can be used with both countables and uncountables, so can be tricky.
how to differentiate? ----> if it can be replaced with a number, then countable, otherwise uncountable. (this hint is written in the paragraph)
a small percentage of our profits ---> three of our profits?
not right , so profits here is an uncountable noun.
a small percentage of our employees ---> three of our employees?
acceptable , so employees is a countable noun.
Generally, profits be countable or uncountable according to the meaning.
Here, it is referring to the revenue in general, not referring to individual profits from different sources.
