The table above shows four numeric expressions. Which expression is an integer when it's evaluated?
A) G
B) F
C) E
D) H
Answer (2)
Evaluate each expression: E = 3.8, F = 0.5, G = -8, H = undefined.
Identify the integer: Only G = -8 is an integer.
The expression that is an integer is G.
The answer is G
Explanation
Understanding the Problem We are given four expressions and we need to determine which one evaluates to an integer. An integer is a whole number (not a fraction) that can be positive, negative, or zero.
Evaluating the Expressions Let's evaluate each expression:
Expression E: 3.8 + 0 = 3.8 . This is not an integer because it has a decimal part.
Expression F: 0 + 0.5 = 0.5 . This is not an integer because it has a decimal part.
Expression G: − 8 + 0 = − 8 . This is an integer.
Expression H: 9 o b re ak o in d e n t ÷ 0 . Division by zero is undefined, so it's not an integer.
Identifying the Integer Therefore, the expression that results in an integer is G, which equals -8.
Examples
Understanding integers is crucial in many real-life situations, such as tracking bank balances (positive or negative whole dollar amounts), counting discrete objects (like the number of apples), or measuring temperature in whole degrees. Recognizing integers helps in making accurate calculations and informed decisions in everyday scenarios.
The expression that evaluates to an integer is expression G, which equals -8. Expressions E and F result in non-integers due to their decimal parts, while expression H is undefined. Therefore, the correct answer is G.
