Question

В саду растут 20 хризантем и 15 ирисов. Сколько процентов от всех цветов составляют ирисы?

Answer 1

По идее:
35 цветов-100%
15 ирисов-х
35х=1500
дальше 1500 на 35 нацело не делится. округляй до 43

Answer 2

35→100%
15→х%
х=(15×100)/35

Answer 3

Calculating the Percentage of Irises in the Garden

To calculate the percentage of irises in the garden, we can use the following formula:

Percentage of Irises = (Number of Irises / Total Number of Flowers) * 100

Given that there are 20 chrysanthemums and 15 irises in the garden, we can calculate the percentage of irises as follows:

Percentage of Irises = (15 / (20 + 15)) * 100

Calculation

Percentage of Irises = (15 / 35) * 100

Percentage of Irises ≈ 42.86%

So, approximately 42.86% of all the flowers in the garden are irises.
