Answer 1

Ответ:

40

Пошаговое объяснение:

Маша прочитала 25% книги

75%= 30 сторінок

Розв'язання:

30ст./75%=0.4

0.4×100%=40 сторінок

Answer 2

This is a math problem. To find out how many pages are in the book Masha is reading, you can use the following formula:

Total pages in the book = Pages read + Pages left to read

In this case: Total pages in the book = 0.25 (pages read) + 30 (pages left to read)

Total pages in the book = 0.25 + 30

Total pages in the book = 30.25

So, the book Masha is reading has 30.25 pages. However, books typically have whole numbers of pages, so we can round this to the nearest whole number. Therefore, Masha's book has approximately 30 pages.
