Answer 1

1) 270 + 270 = 540 цветов было всего

2) 138 + 90 = 228 - было роз и гвоздик

3) 540 - 228 = 312 было лилий и гладиолусов

4) 312 : 4 = 78 - было гладиолусов

5) 78 * 3 = 234 - было лилий

Answer 2

Problem Analysis

To solve this problem, we need to determine the number of lilies in the garden. We are given the following information: - There were 138 roses. - There were 90 carnations (gvozdik). - The number of lilies is three times the number of gladioli. - When half of the flowers were taken away, there were 270 flowers left.

Solution

Let's solve this problem step by step.

Step 1: Let's assume the number of gladioli in the garden is x. Step 2: Since the number of lilies is three times the number of gladioli, the number of lilies is 3x. Step 3: The total number of flowers in the garden is the sum of roses, carnations, gladioli, and lilies. So, the total number of flowers is 138 + 90 + x + 3x. Step 4: When half of the flowers were taken away, there were 270 flowers left. So, the equation becomes (138 + 90 + x + 3x) / 2 = 270.

Now, let's solve the equation to find the value of x and then calculate the number of lilies.

Calculation

Let's solve the equation:

(138 + 90 + x + 3x) / 2 = 270
(228 + 4x) / 2 = 270
228 + 4x = 540
4x = 540 - 228
4x = 312
x = 312 / 4
x = 78

So, the number of gladioli in the garden is 78.

Now, let's calculate the number of lilies:

Number of lilies = 3x = 3 * 78 = 234

Therefore, there were 234 lilies in the garden.

Answer

The number of lilies in the garden was 234.
