To divide fractions, we have to focus on 4 steps, which are:
1: Change to improper fractions
2: Keep the same
3: Change the sign to multiplication
4: Flip the 2nd fraction in the equation
So, step one:
1/3 / 4/5
Step two:
1/3 / 4/5
Step three:
1/3 x 4/5
Step four:
1/3 x 4/5 = (4 / 15)

The scale ratio of a point A to another point B is the division of the length of B by the length of A. The best equation that models the situation is: 
The page dimension is:


The length and the width of Uche's book are equal; this means the pages of Uche's book have the shape of a square
The margin of 0.75 on either sided means the usable dimension is:

The dimension of India is:


The longest side in India's dimension is:

From Uche's book, the longest dimension is:

So, the scale equation is:
k * longest length of Uche's book = longest side of India
This gives:
