b. Sally

John
To determine who ate more of their lunch, we need to compare the portions that Sally and John ate.
Sally ate 5/8 of her lunch, which means she consumed 5 parts out of 8.
John ate 75% of his lunch, which means he consumed 75 parts out of 100.
To compare these fractions, we need to find a common denominator. In this case, we can convert 5/8 to a fraction out of 100 by multiplying the numerator and denominator by 12.
5/8 * 12/12 = 60/96
Now we can compare the fractions:
60/96 (Sally) and 75/100 (John).
To make the comparison easier, we can simplify both fractions.
The simplified fraction for Sally is 5/8 and for John is 3/4.
Comparing these fractions, we can see that 5/8 (Sally) is greater than 3/4 (John).
Therefore, Sally ate more of her lunch than John.
The answer is: b. Sally.
