Answer:

Step-by-step explanation:
Given

Required
Evaluate 
To do this, we simply substitute 2 for b in 


<em>The result of the expression is 10</em>
To get the simplest form of a fraction, simplify or solve it as far as it can be solved. In the case of this fraction for example, both 6 and 18 are divisible by 2. Divisible means both these numbers can be divided by 2.
when we divide them by 2 we get 3 instead of 6 on top and 9 instead of 18 agh the bottom.
6/18 = 3/9
Now 3/9 are both numbers that can further be divided because they can both be divided by 3
this division will give us
1/3 is the answer. This is the simplest form of the fraction 6/18.
