Answer 3

Calculating the Percentage of Pages Read

To calculate the percentage of pages Masha has read, we can use the following formula:

Percentage of pages read = (Pages read / Total pages) * 100

Given that Masha has read 120 pages and has 130 pages left to read, we can calculate the percentage of pages she has read.

Using the formula: Percentage of pages read = (120 / (120 + 130)) * 100

Calculation

Percentage of pages read = (120 / 250) * 100 = 48%

So, Masha has read 48% of the total pages in the book.
