Integer numbers prime factorization: 

26 = 2 * 13; 

50 = 2 * 52;

Take all the common prime factors, by the lowest powers.Greatest (highest) common factor (divisor), gcf, gcd: 
gcf, gcd (26; 50) = 2;

Step 2: Divide fraction's both numerator and denominator by their greatest common factor (divisor), gcf (gcd). 

26
/50 = (2 * 13)/(2 * 52) = ((2 * 13) : 2) / ((2 * 52) : 2) = 13/52 = 13/25

Step 3: Rewrite the end result:13 : 25 = 0.52 as a decimal number.Final answer 
:: written in two ways ::As a proper fraction (ordinary, common): 
26/50 = 13/25; As a decimal number: 
26/50 = 0.52
