i.e.
Where d = daises and r = roses
Convert the above expression to an equation
Make k the subject
When d = 5 and r = 2;
So, the first relationship between d and r can be gotten by substituting 2.5 for k in d = kr
So:
----------- (1)
Make r the subject in (1)
------------------------(2)
Hence, the relationships between d and r are:

Hello ,
40/21 = 21/21 + 19/21
40/21 = 1 + 19/21
40/21 = 1
40/21 = 21/21 + 19/21
40/21 = 1 + 19/21
40/21 = 1
