Answer:
67.5 kg
Step-by-step explanation:
To determine the weight of 45 books, we need to determine the weight of one book, using the equation (30 books = 45 kg). This can be done by dividing 30 to both sides of the equation. Therefore,
- ⇒ 30 books/30 = 45/30 kg
- ⇒ 1 book = 45/30 kg = 3/2 kg = 1.5 kg
We obtained the following equation;
- ⇒ 1 book = 1.5 kg
Now, multiply both sides by 45 to determine the weight of 45 books.
- ⇒ 1 book × 45 = 1.5 kg × 45
- ⇒ 45 books = 67.5 kg
Therefore, the weight of 45 books is 67.5 kg.

[tex]\huge\boxed{\bf{45books = 67.5kg}} [/tex]
Step-by-step explanation:
Given:-
- 30 books = 45kg
To find:-
- 45 books = ?
Ans:-
30books = 45kg
45books = y kg
Let's find 45 books (y)
[tex]\sf \to \frac{30}{45} = \frac{45}{y}[/tex]
[tex]\sf \to 45*45 = 30*y[/tex]
[tex]\sf \to 2,025 = 30*y[/tex]
[tex]\sf \to y = \frac{2,025}{30}[/tex]
[tex]\sf \to y = 67.5kg[/tex]
~therefore 45books = 67.5kg
