Understand the Problem
The question involves determining whether the given numbers are integers or not by evaluating each expression.
Answer
1. Yes 2. No 3. Yes 4. No 5. Yes
Answer for screen readers
- First expression: Yes
- Second expression: No
- Third expression: Yes
- Fourth expression: No
- Fifth expression: Yes
Steps to Solve
- Evaluate Each Expression
We will review each expression to determine if it results in an integer. An integer is a whole number that can be positive, negative, or zero.
- Evaluate $ \frac{8}{4} $
Calculating the first expression: $$ \frac{8}{4} = 2 $$ Since 2 is an integer, we check "Yes".
- Evaluate $ 22.55 $
The second value is already given as 22.55. This is not a whole number. Hence, we check "No".
- Evaluate $ \frac{7}{7} $
Calculating the third expression: $$ \frac{7}{7} = 1 $$ Since 1 is an integer, we check "Yes".
- Evaluate $ \frac{3}{4} $
Calculating the fourth expression: $$ \frac{3}{4} = 0.75 $$ Since 0.75 is not a whole number, we check "No".
- Evaluate $ -76 $
The last number is -76. This is a whole number. Hence, we check "Yes".
- First expression: Yes
- Second expression: No
- Third expression: Yes
- Fourth expression: No
- Fifth expression: Yes
More Information
All evaluated results identify which numbers are integers based on whole number criteria. An integer is defined as a number without fractions or decimals.
Tips
- Confusing fractions that simplify to integers (like $ \frac{8}{4} $) with those that do not (like $ \frac{3}{4} $).
- Assuming decimal numbers are integers; however, decimals like 22.55 are always non-integers.
