Question

Рукопись содержит a страниц.В первый день оператор набрал на компьютере 3/5 всей рукописи,а во второй день 1/4 всей рукописи.Сколько страниц осталось набрать оператору?

Answer 1

3/5 а + 1/4  а = 12/20 а + 5/20 а = 17/20 а
а - 17/20 а = 3/20 а

Answer 2

Calculation of Remaining Pages to be Typed

To calculate the number of pages remaining for the operator to type, we need to determine the total number of pages in the manuscript and subtract the pages already typed by the operator.

Given that the operator typed 3/5 of the manuscript on the first day and 1/4 of the manuscript on the second day, we can calculate the remaining pages as follows:

Let's assume the total number of pages in the manuscript is x.

On the first day, the operator typed 3/5 of the manuscript, which is equal to (3/5)x pages.

On the second day, the operator typed 1/4 of the manuscript, which is equal to (1/4)x pages.

To calculate the remaining pages, we subtract the pages already typed from the total number of pages:

Remaining pages = Total pages - Pages already typed

Remaining pages = x - (3/5)x - (1/4)x

Simplifying the equation:

Remaining pages = x - (3/5)x - (1/4)x Remaining pages = x - (12/20)x - (5/20)x Remaining pages = x - (17/20)x

Therefore, the number of pages remaining for the operator to type is (3/20)x.

Please note that we need the value of x (the total number of pages in the manuscript) to calculate the exact number of remaining pages. Unfortunately, the provided question does not specify the value of x, so we cannot provide an exact answer.
