Final answer:
India's population is 4 times greater than the population of the United States.
Step-by-step explanation:
In 2017, the population of the United States was more than 325 million, while India had almost 1.3 billion people.
To find out how many times greater India's population is compared to the United States, we can divide the population of India by the population of the United States:
India's population / United States' population = 1.3 billion / 325 million = 4
Therefore, India's population is 4 times greater than the population of the United States.
