During the first quarter of the year, 351,875 people downloaded an app for their smartphones. during the second quarter of the year, 101,949 fewer people downloaded the app than during the first quarter. how many downloads occurred during the two quarters of the year? a. round each number to the nearest hundred thousand to estimate how many downloads occurred during the first two quarters ofthe year.

The number of people who downloaded the app in the first quarter is 351,875 people.
Those who downloaded in the second quarter are 101,949 fewer people  than those in first quarter.
This means that:
number of people who downloaded in 2nd quarter = number of people who downloaded in 1st quarter - 101,949
number of people in 2nd quarter = 351,875 - 101,949 = 249,926 people

Therefore, the total number of people who downloaded the app can be calculated as follows:
Total number = 351,875 + 249,926 = 601,801 people

Rounding this number to the nearest hundred thousands, we can get the estimated number of people who downloaded the app as 600,000 people
