Question

У Пети два брата,три сестры и родители.К обеду Петя порезал всю колбасу на круглые кусочки. Сколько Петя сделал разрезов, если каждому досталось по кусочку? Ответ: 7 кусочков

Answer 1

Петя + 2 брата + 3 сестры = 6 детей
6 детей + мама + папа = 8 членов семьи.
То есть кусочков колбасы было 8, для чего Петя сделал 7 разрезов.

Answer 2

Посчитает членов семьи:
Петя - 1 человек
Два брата - 2 человека
Три сестры - 3 человека
Родители - 2 человека
Всего - 1+2+3+2=8 человек
Поэтому разрезов колбасы было 7.

Answer 3

Solution:

To solve this problem, we can use a simple formula to find the number of cuts made by Petia. Since each person gets one piece, the number of cuts is equal to the number of people minus one.

Given: - Number of brothers (B) = 2 - Number of sisters (S) = 3 - Number of parents (P) = 2 - Total number of people = B + S + P + 1 (Petia himself)

Calculation: - Total number of people = 2 (brothers) + 3 (sisters) + 2 (parents) + 1 (Petia) = 8 - Number of cuts = Total number of people - 1 = 8 - 1 = 7

Therefore, Petia made 7 cuts to divide the sausage into equal pieces for everyone.

Explanation:

Petia made 7 cuts to divide the sausage into equal pieces for each family member. This is based on the principle that the number of cuts required to divide a circular object into equal pieces is equal to the number of people minus one.
