Theory:

When multiplying or dividing a monomial by a number, the coefficient of a given monomial is multiplied or divided, but the variable factors remain the same.
Example:
1) Multiply the monomial \(2a\) by \(8\)
2a8=28a=16a
(\(2\) oranges times \(8\) is \(16\) oranges)
  
2) Divide the monomial \(14b\) by \(7\)  
 14b:7=(14:7)b=2b
(if \(14\) bananas are divided equally between \(7\) people, each person will have \(2\) bananas)
 
3) Divide the monomial c by \(10\)   
c:10=(1:10)c=110c=0,1c
(\(1\) lemon divided by \(10\) is \(1\) tenth of a lemon)
