We will say 5 units=3 dollars
1/2 of 5 units=3 dollars (just so I don't get confused)
to find 1/3
times both sides by 2/3 to get
1/3 of 5 units=2 dollars
then times 2 both sides
1/3 of 10 units=4 dollars
so the value of 1/3 of 10 is 4
11 is the only prime number. It's only multiples are 1 and itself
