Hi there! With about 300,000,000 people living the U.S., and 10.7% of the population speak Spanish as their primary language, in order to find the amount of people that speak Spanish as a primary language, we need to multiply the people in the U.S. by the percentage. 300,000,000 * 10.7% (0.107) is 32,100,000. There. About 32.1 million (32,100,000) people speak Spanish as their primary language in the U.S.
