Question

в первый день девочка прочитала 2/5 всей книги а во второй еще 3/10 книги какую часть книги ей осталось прочитать помогите пожалуйста

Answer 1

Ответ:

3/10

Пошаговое объяснение:

Общая длина книги 1/1

1/1 = 2/5 + 3/10 + x

x = 1/1 -2/5 - 3/10

x= 10/10 - 4/10 - 3/10

x = 3/10

Answer 2

Calculating Remaining Book Pages

To calculate the remaining part of the book the girl needs to read, we can use the information provided. On the first day, she read 2/5 of the book, and on the second day, she read 3/10 of the book.

To find out how much of the book she has left to read, we can subtract the pages she has already read from the total number of pages in the book.

The formula to calculate the remaining part of the book is: Total pages - (Pages read on the first day + Pages read on the second day)

Let's calculate it step by step.

Calculation

The total number of pages in the book is not provided, so we'll use a hypothetical total of 50 pages for this example.

1. Pages read on the first day: 2/5 * 50 = 20 pages 2. Pages read on the second day: 3/10 * 50 = 15 pages 3. Total pages read: 20 + 15 = 35 pages 4. Remaining pages: 50 - 35 = 15 pages

So, the girl has 15 pages of the book left to read.
