To solve this problem I had to take off the 2 and make it a one fifths of 20. I had to find how many fives in twenty which is 4. Then you multiply it by the numerator which is 2. So 4x2 is 8, so the answer is 8.
I have tried to explain it best as possible I hope you learn something.
Thank you Eben for sharing your explanation of the method you use. If I am following your method correctly you have identified that one needs to work out the value of the denominator before you can progress to the answer. Can you think of a time that you would need to work out a problem like this in your life?
