Answer 2

What is three-fifths of thirty?
well we can look at this way easier by setting them both up with fractions
and since we don't know the numerator (the top number) for thirty we just put x in its place:) 
  3        x
-----    -----
  5       30

all we need to do is figure out what we multiplied by 5 to get 30
well lets just divide 30 by 5 ...
30 ÷ 5 = 6
so that means that we multiplied 6 to get 30 
in order to get x we do the same to the top number of 3/5 so (3)
3 x 6 = 18 and thats what equals x!
so 3/5s of 30 is 18!
Answer = 18
