can 110/19 be reduced

Question

anonymous · Answer

No because 19 is not a prime factor of 110

anonymous · Answer

on one of my answers for the age thing i got r=110/19
but i need a whole number i think i did this wrong too

anonymous · Answer

my equation that i got was
(r-5)-5=20(r-5)

anonymous · Answer

and when i tryed to solve i got 110/19

anonymous · Answer

are you sure it shouldnt be $$-5(r-5) = 20 (r-5)$$

anonymous · Answer

well the problem says:
Gloria is 20 years older than reggie. five years ago, she was five times as old as he was. how old is each now

anonymous · Answer

The equations you get are 
g = r+20 
g-5 = 5(r-5) =5r-25 
Then need to solve these simultaneously 
ie taking the 2nd - 1st you get -5=4r-45 so 4r=40 r=10 and g=30

anonymous · Answer

oh i know what i did again
 shouldnt my first equation be G=R+20

anonymous · Answer

oh yeah
i keep forgetting that part

anonymous · Answer

20-5 would be 15 right?

anonymous · Answer

or is it negative
