Correct Question is:
Jenny walked 2 3/8 miles on Monday and 1 7/8 miles on Tuesday. How many miles did she walk on Monday and Tuesday all together? What number model would you use?
a. 2 3/8 - 1 7/8
b. 2 3/8 + 1 7/8
c. 23/8 + 17/8
d. none of these
Answer:
b. 2 3/8 + 1 7/8
Explanation:
As the sum of both Monday and Tuesday miles are required therefore both fractions will be added up as mentioned in option B of the question.
remaining are wrong as both fractions cannot be subtracted, and option c is wrong because 2 (3/8) is not equals to 23/8 and 1 (7/8) is not equals to 17/8.
