If x varies directly with y, then :
● Increase in x results in increase of y
● Decrease in x results in decrease of y
● It is represented by : x ∝ y

Here : x₁ = 6 and y₁ = 15 and x₂ = x₂ and y₂ = 20
Substituting the values we get :

Step-by-step explanation:
1. You have the following phrase given in the problem: 16 times as many books. You can conclude this is a multiplication word problem, because:
- Let's call
the number of books.
- "As many boooks" indicates multiplication.
- 16 times means that

Two number : 3,3
So, the GCD of 45,54 is 3×3= 9
