Taking a fraction like '50'/100'. This can be reduced to '1/2'.
How do we do it?
We notice that both '50' and '100' are even number ; end in '0' so they will divide by '2'
So divide top and bottom by '2'
50/100 = 25/50. We now notice that both '25' and '50' end in '5' or '0', so they will divide by '5'
So divide top and bottom by '5'
25/50 = 5/10
We now notice again, that both '5' and '10' end in '5' or '0', so they will divide by '5'
So divide top and bottom by '5'
Hence 5/10 = 1/2
So overall 50/100 = 1/2
NB An appreciation of the multiplication tables is required.
NNB Dividing top and bottom is sometimes referred to as 'cancelling down'.
