Option 3
The solution for given expression is 
<h3><u>
Solution:</u></h3>
Given that we have to divide,
---- (A)
Let us first factorize each term and then solve the sum
Using 
----- (1)
----- (2)
---- (3)
---- (4)
Now substituting (1), (2), (3), (4) in (A) we get,

To do division with fractions, we turn the second fraction upside down and change the division symbol to a multiplication symbol at the same time. Then we treat this as a multiplication problem, by multiplying the numerators and the denominators separately.

On cancelling terms we get,

Thus option 3 is correct
Answer:
9
Step-by-step explanation:
The formula to get the area of a triangle is A=
so all you have to do is work backwards. 18x2=36. 36/4=9.
Answer:
108 books.
Step-by-step explanation:
Let the number of magazines = m
Let the number of books = b
<u>Given the following data;</u>
Total number of m & b = 162
<em>Translating the word problem into an algebraic equation, we have;</em>
......equation 1
......equation 2
<em>Substituting equation "1" into equation "2" we have;</em>
m = 54
Now to find the number of books;

Substituting the value of "m" into the equation, we have;
<em>b = 108</em>
<em>Therefore, the total number of books in the library is 108 books. </em>
