otvet   ostalos 89 stranic

Answer 2

35% = 0,35
180 · 0,35 = 63 (стр.) - было прочитано в первый день.
180 - 63 = 117 (стр.) - оставалось прочитать после первого дня.
117 · 4/9 = 52 (стр.) - прочитано во второй день.
180 - 63 - 52 = 65 (стр.) - осталось прочитать.
Ответ: 65 страниц.

Answer 3

Calculating Remaining Pages to Read

To calculate the remaining pages the boy needs to read, we can follow these steps:

1. Calculate the number of pages read on the first day. 2. Calculate the number of pages read on the second day. 3. Subtract the total pages read from the total number of pages in the book to find the remaining pages.

Step 1: Calculate Pages Read on the First Day

The boy read 35% of the book on the first day.

Calculation: 35% of 180 pages = 0.35 * 180 = 63 pages

Step 2: Calculate Pages Read on the Second Day

On the second day, the boy read 4/9 of the remaining pages.

Calculation: Remaining pages = Total pages - Pages read on the first day Remaining pages = 180 - 63 = 117 pages

4/9 of 117 pages = (4/9) * 117 = 52 pages (rounded to the nearest whole number)

Step 3: Calculate Remaining Pages

To find the remaining pages, subtract the total pages read from the total number of pages in the book.

Calculation: Total pages - Pages read on the first day - Pages read on the second day 180 - 63 - 52 = 65 pages

Answer: The boy has 65 pages left to read in the book.
