Given the expression:
Let's determine the possible sets that the solution of the expression may belong in.
Let's simplify the expression to find the solution:
The solution is -15.
Now, the solution to the expression can be classified as the following:
• Rational number.
A rational number can be said to be any integer, fraction, or decimal.
Therefore, -15 is a rational number
• Integers:
An integer is any whole number that can be negative, positive, or zero.
Therefore, -15 is an integer
• Real number:
A real number is any rational or irrational number.
-15 is a real number.
The solution sets CANNOT be a natural number, whole number, or irrational number.
Therefore, the possible sets are:
• Rational number
,
• Integers
,
• Real number
ANSWER:
• Rational number
