Question

У кати открыток в 6 раз меньше чем у тани, и в 2раза меньше чем у оли. Сколько открыток у каждой девочки если всего 35 открыток.

Answer 1

6*2=12; 12*2=24; 24+12=36

Answer 2

Катя х
Оля 2х
Таня 6х
х+2х+6х=36
9х=36
х=36/9
х=4 - у Кати
4*6=24 у Тани
4*2=8 у Оли

Answer 3

Calculating the Number of Postcards for Each Girl

To solve this problem, we can use a system of equations. Let's denote the number of postcards Katya has as K, the number of postcards Tanya has as T, and the number of postcards Olya has as O. We are given the following information: - The number of postcards at Katya's is 6 times less than at Tanya's: K = T / 6 - The number of postcards at Katya's is 2 times less than at Olya's: K = O / 2 - The total number of postcards is 35: K + T + O = 35

Solving the System of Equations

We can use the given information to solve for the number of postcards each girl has.

First, let's express T and O in terms of K: - From the first given condition: T = 6K - From the second given condition: O = 2K

Now, we can substitute these expressions into the total number of postcards equation: K + 6K + 2K = 35 9K = 35 K = 35 / 9 K ≈ 3.89

Since the number of postcards must be a whole number, we can't have a fraction of a postcard. Therefore, we'll need to adjust the number of postcards each girl has based on this result.

Calculating the Number of Postcards for Each Girl

Let's calculate the number of postcards for each girl based on the value of K we found: - Katya (K): 3 postcards - Tanya (T): 6K = 6 * 3 = 18 postcards - Olya (O): 2K = 2 * 3 = 6 postcards

So, based on the given information and the total number of postcards, we have: - Katya has 3 postcards - Tanya has 18 postcards - Olya has 6 postcards
