Step-by-step explanation: if you have 19.50$ and you buy three separate things then you divide the 19.50 by 3. all you have to do is put your amount in the front (x) and afterwards put your amount of division in the back (y) like so X/Y
First what you need to do is find the HCF of both numbers. After you've done that if it is 1 then they are what we call co-prime. Now, if they are other than 1 they are not co-prime.
