Step-by-step explanation:
let x = 1k and y = 3k, so
\begin{aligned}

To Find,
Solution,
x:y = 1:3 is given to us.
Let a variable a such that x:y= 1a: 3a
and x = a , y = 3a
Now we will put values of x and y in equation,
[ are common so cancel them]
16:15
Hence, ration of (7x^2+3xy) :(2xy+y^2) is 16:15
