TERRIFIC TOP TIPS
Equivalent fingers
If I put up the same number of fingers on each hand, it will be out of 10; take one hand away and I have simplified this to being out of 5.
e.g. 4 fingers on each hand = 8 out of ten
Remove one hand and you now have only 4 fingers out of 5
8/10 = 4/5
Sadly, I cannot use this method for fifths and tenths as I don’t have 10 fingers - only 8!
