5*4 = 20 which is your denominator. Then, you take the numerator(2) and multiply that by four because whatever you do to the bottom, you do to the top. 2*4= 8. The answer is 8/20 which simplifies to 2/5.

math 4th grade
you need to divide 5 by 20. Then with the number that you get you multiply 2 (the numerator). That is your answer. The reason that you take those steps is because whatever you do to the denominator you have to do to the numerator.
