<hr>


"Simplify:9/k+8/k"



{{{9/(k)+8/(k)}}} Start with the given expression



Since the denominators are all equal, we can combine the numerators


{{{(9+8)/(k)}}}   


Now combine like terms


{{{(17)/(k)}}}


So {{{9/(k)+8/(k)=(17)/(k)}}}

#3


"8t/21-5t/21"


{{{8t/21-5t/21}}} Start with the given expression



Since the denominators are all equal, we can combine the numerators


{{{(8-5t)/(21)}}}   



So {{{8t/21-5t/21=(8-5t)/(21)}}}



#4


"Simplify:p/8+3p/8"


{{{p/(8)+3p/(8)}}} Start with the given expression



Since the denominators are all equal, we can combine the numerators


{{{(p+3p)/(8)}}}   


Now combine like terms


{{{(4p)/(8)}}}



{{{(p)/(2)}}} Reduce


So {{{p/(8)+3p/(8)=(p)/(2)}}}
