When you are calculating 39% of 89, I always thought the way was to 89 x 0.39.
I just saw a suggestion, do 89 x 39, then divide by 100. It seems very logical, but never occurred to me. (I don't have a maths brain.)
This method seemed to me a great one, since you don't need to involve decimal multiplication, and all the children doing this should know divide by 100 means moving 2 decimal points to the left.
Is this a valid method in UK?
