Answer:
56%
Explanation:
Percent literally means for each 100 ("cent" coming from the Latin word for 100). All percents can be represented as fractions with 100 in the denominator: 3%, for instance, can be written as 3/100, and 4% as 4/100 (or reduced as 1/25).
We can go the other way with fractions: 3/5 can be written as the fraction 60/100, which is 60%.
In this problem, Ainsley spends 28/50 of her allowance at the coffee shop, which can be written as 56/100, or 56%
