Hoi!
To add fractions with uncommon denominators, we must first find a common denominator of both fractions. To do this, we find the least common multiple.
The least common multiple of 8 and 12 is 24.
Now, how many times do you have to add the denominator of the first fraction to get to 24?
8 + 8 + 8 = 24
3 times. Put the number 3 for the first numerator.
How many times do you have to do the same for the denominator of the second fraction?
12 + 12 = 24
2 times. Put two for the second numerator.
is your answer. :)

Answer: i guess the problem is with P(x) => "x = ", then P(x) is true if that equality is true, and is false if the equality is false.
so lets see case for case.
a) x = 0, and = 0. So p(0) is true.
b) x = 1 and = 1, so P(1) is true.
c) x = 2, and = 4, and 2 ≠ 4, then P(2) is false.
d) x= -1 and = 1, and 1 ≠ -1, so P(-1) is false.
