whats the answer'

The greatest common factor (GCF) of both the numbers 100 and 14 is 2; if you divide the top and bottom by two you get:

$\frac{100}{14}\times\frac{1/2}{1/2}=\frac{50}{7}$

So 50/7 is your most accurate answer; The decimal approximation of this number is:

$\frac{50}{7}\approx7.143...$

the answer is 25
