200:100*45=90 мужчин
200:100*55=110 женщин
=======================
15:30*100=50 деталей
=======================

Answer 2

Question 1: В первый день скосили 34% площади луга, а во второй день ещё 40% первоначальной площади луга. Сколько процентов площади луга скосили за два дня?

To find out how much of the total area of the meadow was mowed in two days, we can add the percentages of the area mowed on each day.

- On the first day, 34% of the meadow was mowed. - On the second day, an additional 40% of the original meadow area was mowed.

To calculate the total percentage of the meadow area mowed in two days, we add the percentages: 34% + 40% = 74%.

Answer: 74% of the meadow area was mowed in two days.

Question 2: В санатории отдыхают 200 человек. Среди них 45% мужчины. Сколько мужчин и женщин отдыхают в санатории?

To find out the number of men and women in the sanatorium, we need to calculate the number of men and women based on the given percentage.

- The total number of people in the sanatorium is 200. - 45% of them are men.

To calculate the number of men, we multiply the total number of people by the percentage of men: 200 * 45% = 90 men.

To calculate the number of women, we subtract the number of men from the total number of people: 200 - 90 = 110 women.

Answer: There are 90 men and 110 women in the sanatorium.

Question 3: Слесарь изготовил 15 деталей, что составляет 30% плана. Сколько деталей должен изготовить слесарь по плану?

To find out how many parts the locksmith should produce according to the plan, we need to calculate the total number of parts based on the given percentage.

- The locksmith has already produced 15 parts, which is 30% of the plan.

To calculate the total number of parts according to the plan, we divide the number of parts produced by the percentage achieved: 15 / 30% = 50 parts.

Answer: The locksmith should produce 50 parts according to the plan.

Question 4: В классе 25 учеников. На занятиях отсутствует трое. Сколько процентов учеников отсутствует?

To find out the percentage of students absent from class, we need to calculate the number of absent students and then express it as a percentage of the total number of students.

- The total number of students in the class is 25. - Three students are absent.

To calculate the percentage of absent students, we divide the number of absent students by the total number of students and multiply by 100: (3 / 25) * 100 = 12%.

Answer: 12% of the students are absent from class.

Question 5: Вычислите 50% суммы чисел 250, 360, 410.

To calculate 50% of the sum of the numbers 250, 360, and 410, we first need to find the sum of these numbers and then calculate 50% of that sum.

- The sum of the numbers 250, 360, and 410 is 1020.

To calculate 50% of the sum, we multiply the sum by 50% (or 0.5): 1020 * 0.5 = 510.

Answer: 50% of the sum of 250, 360, and 410 is 510.

Question 6: При хранении денег в Сбербанке начисляется 6% годовых. На счете у вкладчика находится сумма денег, равная 50000р. Сколько денег станет на этом счете через 1 год?

To calculate the amount of money that will be on the account after 1 year with an annual interest rate of 6%, we need to calculate the interest earned and add it to the initial amount.

- The initial amount on the account is 50000 rubles. - The annual interest rate is 6%.

To calculate the interest earned, we multiply the initial amount by the interest rate: 50000 * 6% = 3000 rubles.

To calculate the total amount on the account after 1 year, we add the interest earned to the initial amount: 50000 + 3000 = 53000 rubles.

Answer: There will be 53000 rubles on the account after 1 year.
