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.


Here is some additional details about this question. Determine whether sum is reasonable. Compare addends to benchmark 0 and 1/2.

Plz help with an explanation what step to
Follow to understand this question. Thank you!

To understand this question, we need to determine if the sum of 3/8 and 1/8 is reasonable. The options given are 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, and D) It is not reasonable because 1/2 + 1/2 = 1.

To solve this question, we need to add 3/8 and 1/8 together. We can do this by finding a common denominator. In this case, the common denominator is 8.

To convert 3/8 to a fraction with a denominator of 8, we need to multiply the numerator and denominator by 2:
(3/8) * (2/2) = 6/16

To convert 1/8 to a fraction with a denominator of 8, we need to multiply the numerator and denominator by 1:
(1/8) * (1/1) = 1/8

Now, we can add the fractions together:
6/16 + 1/8 = 7/16 + 1/8

To add the fractions, we need a common denominator. The common denominator for 16 and 8 is 16.

Now, we can add the numerators together and keep the denominator the same:
(7/16) + (2/16) = 9/16

The sum of 3/8 and 1/8 is 9/16.

Now, we can compare the sum of 9/16 to the options given. None of the options given match the sum of 9/16. Therefore, none of the options given accurately describe the sum.

So, the answer is that none of the options accurately describe the sum 7/8.
