In this case '7' is as common factor to both numbers. 1 x 7 = 7 4 x 7 = 28 As you can see '7' has a factor of '1' and '28' has a factor of '4',so you cancel down/reduce by a factor of '7' to leave '1' & ''4'. Hence 7/28 = 1/4 This method is good for any fraction, but the two numbers MUST have a common factor.
