Question

в книге 170 страниц.максим в первый день прочитал 2_5 а во второй-3_10 книг.больше или меньше половины книги прочитал максим за эти два дня?сколько страниц ему осталось прочитать?сравните эту задачу с предыдущей.в чем их сходство?в чем отличие?

Answer 1

1) 4/10 + 3/10 = 7/10 да, больше
2) 3/10 * 170 =  51
3) с какой задачей?

Answer 2

Problem Analysis

In this problem, we are given that Maxim read 2/5 of a book on the first day and 3/10 of the book on the second day. We need to determine if Maxim read more or less than half of the book in these two days and calculate how many pages he has left to read. We are also asked to compare this problem with the previous one and identify their similarities and differences.

Solution

To solve this problem, we need to calculate the total fraction of the book that Maxim read in the two days and compare it to half of the book. Let's calculate the fraction of the book that Maxim read on each day:

- On the first day, Maxim read 2/5 of the book. - On the second day, Maxim read 3/10 of the book.

To find the total fraction of the book that Maxim read, we can add these two fractions together:

2/5 + 3/10 = 4/10 + 3/10 = 7/10

So, Maxim read 7/10 of the book in these two days.

Now, let's compare this fraction to half of the book. Half of the book can be represented as 1/2.

To determine if Maxim read more or less than half of the book, we can compare the fractions:

7/10 > 1/2

Since 7/10 is greater than 1/2, Maxim read more than half of the book in these two days.

To calculate the number of pages Maxim has left to read, we need to subtract the fraction of the book he read from 1 (the whole book). Let's calculate this:

1 - 7/10 = 3/10

So, Maxim has 3/10 of the book left to read.

Comparison with the Previous Problem

The previous problem involved a similar scenario where Maxim read a certain fraction of a book on different days. The similarities between the two problems are as follows:

1. Both problems involve calculating the fraction of a book that Maxim read on different days. 2. In both problems, we need to compare the fraction of the book read to half of the book. 3. The calculations involved in both problems are similar, as we need to add fractions and compare them to a specific fraction.

The main difference between the two problems is the specific fractions given for each day's reading.

Summary

In summary, Maxim read more than half of the book in the two days, as he read 7/10 of the book. He has 3/10 of the book left to read. This problem is similar to the previous one in terms of calculating fractions of a book read on different days, but the specific fractions given for each day are different.
