One day 3/8 of the students in Jack's class ate toast for breakfast. Another 1/8 of the students ate oatmeal. Jack added the fractions and found the sum was 7/8. Which statement best describes the sum 7/8?
A) It is reasonable because 1/2 + 0 = 1/2.
B) It is reasonable because 1/2 + 1/2 = 1.
C) It is not reasonable because 1/2 + 0 = 1/2.
D) It is not reasonable because 1/2 + 1/2 = 1.
Plz help with an explanation what step to
Follow to understand this question. Thank you!
"Which statement best describes the sum 7/8? "
- first of all 7/8 is not the "sum"
- secondly, there is no mathematical reason for Jack to come up with 7/8
- thirdly , this is a silly question.
Here is some additional details about this question. Determine whether sum is reasonable. Compare addends to benchmark 0 and 1/2. Thanks!
To understand this question, you need to understand the concept of adding fractions. Follow these steps to solve the problem:
1. Calculate the fraction of students who ate toast: 3/8.
2. Calculate the fraction of students who ate oatmeal: 1/8.
3. Add the fractions together: 3/8 + 1/8 = 4/8.
4. Simplify the fraction if possible: 4/8 simplifies to 1/2.
Now, let's analyze the given options:
A) It is reasonable because 1/2 + 0 = 1/2.
This option is incorrect because the given sum is 7/8, not 1/2.
B) It is reasonable because 1/2 + 1/2 = 1.
This option is incorrect because the given sum is 7/8, not 1.
C) It is not reasonable because 1/2 + 0 = 1/2.
This option is incorrect because the given sum is 7/8, not 1/2.
D) It is not reasonable because 1/2 + 1/2 = 1.
This option is incorrect because the given sum is 7/8, not 1.
Therefore, none of the given options accurately describe the sum 7/8.
To understand this question, you need to follow these steps:
1. Read the question carefully to understand what is being asked.
2. Analyze the information provided: In the question, it is mentioned that 3/8 of the students ate toast and another 1/8 ate oatmeal. The sum of these fractions is 7/8.
3. Compare the sum of the fractions (7/8) with the given options.
4. Evaluate each option by applying the operation described, and check if the result matches the given sum of 7/8.
Let's now go through each statement:
A) It is reasonable because 1/2 + 0 = 1/2.
This option involves adding 1/2 and 0, which doesn't match the given fractions in the question. Thus, this statement is not the correct choice.
B) It is reasonable because 1/2 + 1/2 = 1.
Here, the operation involves adding 1/2 and 1/2, which equals 1. However, the given sum in the question is 7/8, not 1. Therefore, this statement is also not correct.
C) It is not reasonable because 1/2 + 0 = 1/2.
Similar to option A, this statement involves adding 1/2 and 0, which doesn't match the given fractions. Thus, this statement is also incorrect.
D) It is not reasonable because 1/2 + 1/2 = 1.
This option involves adding 1/2 and 1/2, which equals 1. However, the given sum in the question is 7/8, not 1. Hence, this statement is not the correct answer either.
The only option remaining is D) It is not reasonable because 1/2 + 1/2 = 1. This choice correctly points out that the given sum of 7/8 does not match the result of adding 1/2 and 1/2. Therefore, the correct statement is D).
In conclusion, the statement that best describes the sum 7/8 is D) It is not reasonable because 1/2 + 1/2 = 1.
