Question

Решите задачу Оля и Яло попали на хобот куда городу спускаться с лестницы из трех пролетов первом полете было 60 ступенек что в 3 раза больше чем во втором в 4 раза больше чем в третьем про людей с лица девочки прошли пятую часть всех ступенек лестницы Сколько ступенек им осталось пройти

Answer 1

60/3=20 ст - 2 пролет
60/4=15 ст- 3 пролет
60+20+15=95 ст - всего
95/5=19 ст - прошли
95-19=76 ст -осталось пройти

Answer 2

Problem Analysis

The problem states that Olya and Yalo are descending a staircase with three flights. The number of steps in the first flight is three times the number of steps in the second flight, and the number of steps in the second flight is four times the number of steps in the third flight. Additionally, the girls have already descended one-fifth of all the steps on the staircase. We need to determine how many steps they have left to descend.

Solution

Let's denote the number of steps in the third flight as x. According to the problem, the number of steps in the second flight is four times x, and the number of steps in the first flight is three times the number of steps in the second flight.

So, the number of steps in the second flight is 4x, and the number of steps in the first flight is 3(4x) = 12x.

The total number of steps on the staircase is the sum of the steps in all three flights: x + 4x + 12x = 17x.

Since the girls have already descended one-fifth of all the steps, the number of steps they have left to descend is four-fifths of the total number of steps: (4/5) * 17x = (68/5)x.

To find the number of steps they have left to descend, we need to determine the value of x.

Calculation

Unfortunately, the search results provided do not contain the necessary information to determine the value of x. Therefore, we are unable to provide a specific numerical answer to the problem.

However, we can still provide the general formula to calculate the number of steps the girls have left to descend, which is (68/5)x.

Answer

The number of steps Olya and Yalo have left to descend is (68/5)x, where x represents the number of steps in the third flight.
