This was the one question that stumped me. Thank you for explaining!

could you also just divide 20 by 50? when I did that I got the same answer?

I was thinking that multiplying 20 by 5 making 100 would make it easier to understand and so by also multiplying 8 by 5 which is 40, you can convert it to decimal thinking of it as a percentage
