Note that because every 2-element subset chosen from a set of 5 elements corresponds to a unique 3-element subset consisting of the elements not chosen.
My questions concern whether consisting of the elements not chosen is a relative clause (transormed from: subest which consists of...) or is the gerund a object complement.
The number of digits to the right of the decimal point is equal to the sum of the numbers of digits to the right of the decimal points in the number being multiplied.
Is being multiplied a reduced relative clause(transformed from: the number which is being multiplied) or is the gerund an object complement?
I have trouble making a distinction because the following website says (https://www.thefreedictionary.com/Object-Complements.htm):
"Participles generally function as object complements by describing what the direct object is or was doing."
