Final answer:
To evaluate the expression 1/3 + 1, we express 1 as a fraction with a denominator of 3, making it 3/3. Adding the numerators, we get 1 + 3 = 4, so the answer is 4/3 or 1 1/3 as a mixed number.
Step-by-step explanation:
To evaluate the expression 1/3 + 1, we start by understanding that adding 1 (which is a whole number) to a fraction involves converting the whole number into a fraction with the same denominator as the fraction we are adding to.
To evaluate the expression 1/3 + 1, we need to find a common denominator. The common denominator for 1/3 and 1 is 3. We convert 1 to the fraction 3/3, so the expression becomes 1/3 + 3/3. Adding the numerators, we get 4/3. Since the denominator remains the same, our final answer is 4/3.
In this case, we want to express 1 as a fraction with a denominator of 3. Therefore, 1 is the same as 3/3. Now our expression looks like:
1/3 + 3/3
We then add the numerators together while keeping the denominator the same:
1 + 3 = 4
So, our new numerator is 4 and the denominator remains 3:
4/3
Therefore, the expression 1/3 + 1 evaluates to 4/3, which is also known as 1 1/3 when expressed as a mixed number.
