So,

In order to simplify a fraction, we have to factor both the numerator and the denominator.
[tex] \frac{420}{15} --\ \textgreater \ \frac{2*2*3*5*7}{3*5} [/tex]

Cross out ones.
[tex]\frac{2*2*7}{1}\ or\ 28[/tex]

for simplifying 420/15 we check if these both numbers are divisible by any one number ...
here these no:s can be divided by 5 ..

450/15 =84/3 = 28/1 ....
therefore the simplified form of 420/15 is 28/1 or 28 ...

Hope it helps !!!
