If you see twice as many X's, or [i]half as many X's, or three times this/that number of X's, etc. -- just treat it in the same way you'd treat "two X's" or "twenty X's" or whatever.
So:
Two trucks came off the assembly line.
Twice as many trucks came off the assembly line.
Three times the previous number of trucks came off the assembly line.
Etc.
