books on the shelf.
How much thicker is Amalie's book than Raj's book?

The difference in their thickness is:

Step-by-step explanation:

Given

The attached plot which represents thickness of books

Required

Difference in the thickness of Amalie's (A) and Raj's (R)

From the question, we understand that:

Thickest

One of the least

This implies that:

The difference (d) is:

vbbv

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
