Question

В альбоме родителей 405 фотокарточек,а в альбоме бабушки с дедушки-в 3 раза меньше. На сколько больше фотокарточек у родителей,чем бабушки с дедушкой? Алёша узнал себя на четверти всех фотокарточек.Сколько всего карточек с изображением Алёши?

Answer 1

У б. с .д. карточек вдвое меньше, чем у родителей, следовательно
1) 405/3=135 (карточек у бабушки с дедушкой)
Чтобы узнать на сколько меньше карточек, нужно отнять большее число от меньшего
2) 405-135=270 (больше у родителей карточек на это число)
Алеша узнал себя на четверти всех фото, значит нужно для начала найти общее количество фото
3) 405+135=540 (карточек всего)
чтобы найти четверть от этого числа, нужно разделить на четыре
4) 540/4 = 135 (карточек с изображением Алеши)

Answer 2

Calculating the Number of Photographs

To calculate the number of photographs in each album and find out how many more photographs the parents have compared to the grandparents, we can use the following information:

- The parents have 405 photographs in their album. - The grandparents have three times fewer photographs than the parents.

Let's calculate the number of photographs in the grandparents' album and then find the difference.

Step 1: Calculate the number of photographs in the grandparents' album. Step 2: Find the difference in the number of photographs between the parents and the grandparents.

Step 1: Calculate the Number of Photographs in the Grandparents' Album

The number of photographs in the grandparents' album can be calculated by dividing the number of photographs in the parents' album by 3.

405 / 3 = 135

According to the given information, the grandparents have 135 photographs in their album.

Step 2: Find the Difference in the Number of Photographs

Now, let's find the difference in the number of photographs between the parents and the grandparents.

405 - 135 = 270

The parents have 270 more photographs than the grandparents.

Calculating the Total Number of Photographs with Aleesha's Image
