Question

В первом ряду кустов смородины в 2,5 раза больше, чем во втором. Если с первого ряда пересадить 12 кустов на второй, то количество кустов смородины станет одинаковым. сколько кустов смородины было во втором ряду первоначально.?

Answer 1

Х - во втором ряду
2,5х - в первом
2,5х-12=х+12
2,5х-х=12+12
1,5х=24
х=24:1,5
х=16 кустов - во втором ряду

Answer 2

Х - во втором ряду
2,5х - в первом ряду
2,5х-12=х+12
2,5х-х=12+12
1,5х=24
х=24:1,5
х=16 (кустов)
Ответ: первоначально во втором ряду было 16 кустов

Answer 3

Solution

Let's solve the problem step by step.

Given Information

- The number of currant bushes in the first row is 2.5 times greater than in the second row. - If 12 bushes are transplanted from the first row to the second, the number of currant bushes will become the same in both rows.

Step 1: Setting up Equations

Let's denote the number of bushes in the second row as x. Then the number of bushes in the first row will be 2.5x. After transplanting 12 bushes from the first row to the second, the number of bushes in both rows will be equal.

Step 2: Solving the Equations

We can set up the equation: 2.5x - 12 = x

Step 3: Calculating the Number of Bushes in the Second Row

Let's solve for x to find the number of bushes in the second row.

2.5x - 12 = x 1.5x = 12 x = 12 / 1.5 x = 8

So, initially, there were 8 currant bushes in the second row.

Therefore, the initial number of currant bushes in the second row was 8.
