Step-by-step explanation:
Given proportion is 2 1/2 :x::3 1/2 :4
It can be written as 5/2:x:7/2:4
Product of extremes=(5/2)×4=5×2=10
Product of means=x×7/2=7x/2
We know that
In a proportion,
Product of means=Product of extremes
=>7x/2=10
=>7x=10×2
=>7x=20
=>x=20/7
=>x=2 6/7
The value of x=20/7 or 2 6/7
