Question

В первый киоск привезли 120 конвертов,во второй 150. конверты в каждом киоске разложили поровну в пачки.при этом во втором киоске получилось на 3 пачки с конвертами больше, чем в первом. сколько пачек с конвертами получилось в каждом киоске?

Answer 1

(150-120)÷3=10(к) было в 1 пачке
120÷10=12(п) с конвертами в 1 киоске
150÷10=15(п) с конвертами в 2 киоске

ответ: 12 пачек с конвертами в 1 киоске и 15 пачек с конвертами во 2 киоске получилось

Answer 2

В первом 12,а во втором 15

Answer 3

Problem Analysis

We are given two kiosks, the first one with 120 envelopes and the second one with 150 envelopes. The envelopes are distributed equally into packs in each kiosk. However, in the second kiosk, there are 3 packs more than in the first kiosk. We need to determine the number of packs with envelopes in each kiosk.

Solution

Let's assume that there are x packs in the first kiosk and x + 3 packs in the second kiosk.

To find the number of envelopes in each pack, we can divide the total number of envelopes in each kiosk by the number of packs.

Let's solve the problem step by step:

1. Calculate the number of envelopes in each pack in the first kiosk: - Total number of envelopes in the first kiosk: 120 - Number of packs in the first kiosk: x - Number of envelopes in each pack in the first kiosk: 120 / x

2. Calculate the number of envelopes in each pack in the second kiosk: - Total number of envelopes in the second kiosk: 150 - Number of packs in the second kiosk: x + 3 - Number of envelopes in each pack in the second kiosk: 150 / (x + 3)

3. Set up an equation to represent the relationship between the number of envelopes in each pack in the first and second kiosks: - Number of envelopes in each pack in the first kiosk = Number of envelopes in each pack in the second kiosk

This can be written as: 120 / x = 150 / (x + 3)

4. Solve the equation to find the value of x: - Multiply both sides of the equation by x and (x + 3): 120 * (x + 3) = 150 * x - Expand and simplify the equation: 120x + 360 = 150x - Subtract 120x from both sides of the equation: 360 = 30x - Divide both sides of the equation by 30: x = 12

5. Calculate the number of packs in each kiosk: - Number of packs in the first kiosk: x = 12 - Number of packs in the second kiosk: x + 3 = 12 + 3 = 15

Therefore, there are 12 packs with envelopes in the first kiosk and 15 packs with envelopes in the second kiosk.

Answer

In the first kiosk, there are 12 packs with envelopes, and in the second kiosk, there are 15 packs with envelopes.
