Answer:
[] Noah shares 7 grapes with 3 friends. He eats 1 and gives each friend the same number of grapes.
[] Andre studies 7 hours this week for end-of-year exams. He spends 1 hour on English and an equal number of hours each on math, science, and history.
Reasoning:
[✗] The first story, with Diego, does not work because the whole is $1 in the problem and $7 in the diagram.
[✗] The second story, with Elena, does not work because the 7 is ignored entirely and the x becomes a known value, 57.
[✓] The third story, with Noah, does work because he splits seven grapes equally among three friends (the x's) and eats one.
[✓] The fourth story, with Andre, does work because 7 hours were spent studying. One on English and the rest (three subjects) split evenly (x).
[✗] The fifth story, with Lin, does not work because the total is $3 when it should be 7.
Have a nice day!
