Final answer:
To find the total calories in 2 1/2 slices of bread, where each slice is 80 calories, multiply 2 by 80 to get 160 for two slices, and divide 80 by 2 to get 40 for half a slice. Add these to get a total of 200 calories.
Step-by-step explanation:
The question is asking for the total number of calories in 2 1/2 slices of bread, given that one slice contains 80 calories. To find the answer, you can use multiplication and addition. First, calculate the calories in 2 slices by multiplying the number of slices by the calories per slice: 2 slices × 80 calories/slice = 160 calories. Then, calculate the calories in half a slice by dividing the calories per slice by 2: 80 calories/slice ÷ 2 = 40 calories.
Finally, add the calories of 2 slices and half a slice together to get the total: 160 calories + 40 calories = 200 calories. Therefore, there are 200 calories in 2 1/2 slices of bread.
To find the number of calories in 2 1/2 slices of bread, we need to multiply the calories in one slice of bread by 2 1/2. Since one slice of bread is 80 calories, we can calculate:
80 calories * 2.5 = 200 calories
So, approximately, there are 200 calories in 2 1/2 slices of bread.
