An

**accidental cancellation**is reducing a fraction by canceling individual digits in the numerator and denominator.

In some cases the result is equal to that obtained by a correct process.

Examples:

**16/64 = 1**~~6~~/~~6~~4 = 1/4;

26/65 = 2~~6~~/~~6~~5 = 2/5;

266/665 = 2~~66~~/~~66~~5 = 2/5;

4~~9~~/~~9~~8 = 4/8 = 1/2 etc.

Try to find two-digit cases in bases other than base 10,(e.g. 13/32 = 1/2 ( the only solution in base 4).

26/65 = 2

266/665 = 2
