Question

Для школьного оркестра купили две гитары и домбр в 6 раз больше чем гитар а кабызов в 7 раз меньше чем гитар и домбр вместе взятых Сколько всего музыкальных инструментов купили для оркестра

Answer 1

2*6 = 12 домбр
2+12 = 14 гитар и домбр вместе
14:7 = 2 кабыза
14+2 = 16 всего инструментов.

Answer 2

1) 2х6=12(шт)-купили домбр
2) (2+12):7=2(шт)- купили кабызов
3) 2+12+2=16(шт)- купили всего инструментов

Answer 3

Solution:

To solve this problem, we can use a system of equations to represent the given information and then solve for the total number of musical instruments purchased for the orchestra.

Let's denote: - the number of guitars as G - the number of dombras as D - the number of kabyzes as K

We are given the following information: 1. D = 6G (The number of dombras is 6 times the number of guitars) 2. K = (1/7)G (The number of kabyzes is 1/7 times the number of guitars) 3. G + D + K = Total number of musical instruments

We can use the first two equations to express D and K in terms of G and then substitute these expressions into the third equation to solve for the total number of musical instruments.

Calculation:

Using the given information: 1. D = 6G 2. K = (1/7)G

Substituting the values of D and K into the equation G + D + K = Total number of musical instruments: G + 6G + (1/7)G = Total number of musical instruments 7G + 42G + G = Total number of musical instruments 50G = Total number of musical instruments

So, the total number of musical instruments purchased for the orchestra is 50G.

Conclusion:

The total number of musical instruments purchased for the orchestra is 50 times the number of guitars.
