Question

ДАЮ ВСЕ БАЛЛЫ, ТОЧНЫЙ ОТВЕТ БЕЗ СПАМА Белла запланировала прочитать книгу. В первый день она прочла 1/4 всей книги, а во второй день 20% оставшейся части. Сколько страниц книги осталось прочитать Белле после двух этих дней, если всего в книге 480 страниц?

Answer 1

Ответ:

Пошаговое объяснение:

20% = 20 : 1 00 = 0,2

1) 480 * 1/4 = 480/4 = 120 (стр) - прочитала в 1 день

2) 480 - 120 = 360 (стр) - осталось прочитать после 1 дня

3) 0,2 * 360 = 72 (стр) - прочитала во 2 день

4) 120 + 72 = 192 (стр) - прочитала за два дня

5) 480 - 192 = 288 (стр) - осталось прочитать

Ответ: 288 страниц

Answer 2

Calculating Remaining Pages to Read

To calculate the remaining pages for Bella to read after the two days, we can follow these steps:

1. Calculate the number of pages Bella read on the first day. 2. Calculate the number of pages remaining after the first day. 3. Calculate the number of pages Bella read on the second day. 4. Calculate the number of pages remaining after the second day.

Let's start with the calculations.

1. Pages Read on the First Day: Bella read 1/4 of the entire book on the first day. 1/4 of 480 pages = (1/4) * 480 = 120 pages read on the first day.

2. Pages Remaining After the First Day: Pages remaining after the first day = Total pages - Pages read on the first day Pages remaining after the first day = 480 - 120 = 360 pages remaining.

3. Pages Read on the Second Day: Bella read 20% of the remaining pages on the second day. 20% of 360 pages = (20/100) * 360 = 72 pages read on the second day.

4. Pages Remaining After the Second Day: Pages remaining after the second day = Pages remaining after the first day - Pages read on the second day Pages remaining after the second day = 360 - 72 = 288 pages remaining.

Therefore, after the two days, Bella has 288 pages of the book left to read.

This calculation is based on the given information and the formula for calculating percentages and fractions.
