Answer:
To find the percentage of people in the world who speak Spanish, we can use the following formula:
percentage = (part/whole) x 100%
where "part" is the number of people who speak Spanish and "whole" is the total world population.
Substituting the given values, we get:
percentage = (527/7,530) x 100% ≈ 7.00%
Rounding to the nearest whole percent, we get that approximately 7% of people in the world speak Spanish.
