During the first quarter of the year, 351,875 people downloaded an app for their smartphones. During the second quarter of the y
Lina20 [59]
The number of people who downloaded the app in the first quarter is 351,875 people.
Those who downloaded in the second quarter are <span>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 = </span>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

2/5- -3/4 what would be the answer?
Ipatiy [6.2K]

For this case we must simplify the following expression:

\frac {2} {5} - (- \frac {3} {4})

By definition of the law of multiplication signs we have to:

- * - = +

So, rewriting the expression we have:

\frac {2} {5} + \frac {3} {4} =\\\frac {4 * 2 + 5 * 3} {5 * 4} =\\\frac {8 + 15} {20} =\\\frac {23} {20} = 1.15

Thus, the answer in decimal form is 1.15.

Answer:

\frac {23} {20} = 1.15
