Question

в лесу 4% птиц составляет дятлы 25% от оставшийся птиц кукушки.25% от нового остатка филины а остальные другие виды птиц ..сколько процентов в лесу других видо... подробно с условием должен быть ответ 54 %

Answer 1

изначально было 100% птиц.

из них 4 % дятлы, значит других птиц 96%.

кукушки - составляют 25% от 96% (96*0,25) - получается что кукушек 24%

после кукушек осталось 96-24=72%птиц других видов

из этих 72% птиц 25 процентов филинов, то есть их (72*0,25)=18%

теперь вычитаем из 72%  25 % и получаем, что других видов 54%

Answer 2

Solution:

Let's solve the problem step by step.

Given: - 4% of the birds in the forest are woodpeckers. - 25% of the remaining birds are cuckoos. - 25% of the new remainder are owls, and the rest are other types of birds.

We need to find the percentage of other bird species in the forest.

Step 1: Calculate the Percentage of Cuckoos

First, let's calculate the percentage of cuckoos in the forest: - 4% woodpeckers leaves 96% of the birds. - 25% of the remaining 96% are cuckoos.

So, the percentage of cuckoos in the forest is 96% * 25% = 24%.

Step 2: Calculate the Percentage of Owls

Next, let's calculate the percentage of owls in the forest: - After accounting for woodpeckers and cuckoos, 75% of the birds remain. - 25% of this new remainder are owls.

So, the percentage of owls in the forest is 75% * 25% = 18.75%.

Step 3: Calculate the Percentage of Other Bird Species

Finally, let's calculate the percentage of other bird species in the forest: - We have already calculated the percentages of woodpeckers, cuckoos, and owls. - The remaining percentage of bird species in the forest is 100% - (4% + 24% + 18.75%) = 53.25%.

Therefore, the percentage of other bird species in the forest is 53.25%.

Conclusion:

After performing the calculations, it can be concluded that 53.25% of the birds in the forest belong to other bird species.
