Question

в розовой стране 540000жителей что составиляет 9\10 (девять десятых )жителей голубой страны , в желтой стране живёт 4о % (сорок сотых) от общего числа жителей розовой и голубой стран , а в фиолетовой стране - на 78000 жителей больше , чем в желтой стране точка Сколько жителей в изумрудном городе , если всего в волшебной стране насчитывается 3000000 (3милионов)жителей?

Answer 1

сколько живёт в голубой стране

540 000*10:9= 600 000 чел

сколько живёт в розовой и голубой странах

540 000+600 000= 1 140 000 чел

сколько в жёлтой

1 140 000:100*40= 456 000 чел

сколько живёт в фиолетовой

78 000+ 456 000= 534 000 чел

сколько жителей в изумрудном городе

3 000 000 - 540 000-600 000 -456 000-534 000=870 000 чел

Answer 2

540 000*10:9= 600 000 чел в голубой стране

540 000+600 000= 1 140 000 чел в розовой и голубой странах

1 140 000:100*40= 456 000 чел в жёлтой

78 000+ 456 000= 534 000 чел живёт в фиолетовой

3 000 000 - 540 000-600 000 -456 000-534 000=870 000 чел в изумрудном городе

Answer 3

Calculation of Population in Different Countries

To calculate the population in the Emerald City, we need to analyze the given information about the population in the Pink, Blue, Yellow, and Violet countries.

According to the information provided: - The Pink country has a population of 540,000, which is 9/10 (nine-tenths) of the population of the Blue country. - The Yellow country has a population that is 4/100 (four-hundredths) of the combined population of the Pink and Blue countries. - The Violet country has a population that is 78,000 more than the population of the Yellow country.

Let's break down the calculations step by step.

Population in the Blue Country

The population in the Pink country is 9/10 of the population in the Blue country. Therefore, we can calculate the population in the Blue country by dividing the population in the Pink country by 9/10.

Population in the Blue country = Population in the Pink country / (9/10)

Population in the Yellow Country

The population in the Yellow country is 4/100 of the combined population of the Pink and Blue countries. To calculate the population in the Yellow country, we need to add the populations of the Pink and Blue countries and then multiply it by 4/100.

Population in the Yellow country = (Population in the Pink country + Population in the Blue country) * (4/100)

Population in the Violet Country

The population in the Violet country is 78,000 more than the population in the Yellow country. Therefore, we can calculate the population in the Violet country by adding 78,000 to the population in the Yellow country.

Population in the Violet country = Population in the Yellow country + 78,000

Population in the Emerald City

To calculate the population in the Emerald City, we need to add the populations of all the countries: Pink, Blue, Yellow, and Violet.

Population in the Emerald City = Population in the Pink country + Population in the Blue country + Population in the Yellow country + Population in the Violet country

Now, let's perform the calculations using the given information.

Calculation Steps:

1. Calculate the population in the Blue country using the population in the Pink country. 2. Calculate the population in the Yellow country using the populations in the Pink and Blue countries. 3. Calculate the population in the Violet country using the population in the Yellow country. 4. Calculate the population in the Emerald City using the populations in all the countries.

Calculation Results:

1. Population in the Blue country = 540,000 / (9/10) = 600,000 [[1]] 2. Population in the Yellow country = (540,000 + 600,000) * (4/100) = 54,000 [[2]] 3. Population in the Violet country = 54,000 + 78,000 = 132,000 [[3]] 4. Population in the Emerald City = 540,000 + 600,000 + 54,000 + 132,000 = 1,326,000

Therefore, the population in the Emerald City is 1,326,000.
