скриншот условия
15. Какой процент составляют числа, делящиеся на 5, от чисел последовательности 13; 14; 15; 16; 17; 18; 19; 20:
A) 50%;
B) 75%;
C) 20%;
D) 25%;
E) 30%?
Решение. №15 (с. 66)
Решение 2. №15 (с. 66)
Для решения этой задачи необходимо определить, какую часть от общего количества чисел в последовательности составляют числа, делящиеся на 5, и затем выразить эту часть в процентах.
1. Сначала посчитаем общее количество чисел в предоставленной последовательности: 13, 14, 15, 16, 17, 18, 19, 20. Всего в последовательности 8 чисел.
2. Далее определим, какие из этих чисел делятся на 5 без остатка. Число делится на 5, если его последняя цифра равна 0 или 5. В данной последовательности это числа 15 и 20. Таким образом, у нас есть 2 числа, удовлетворяющих этому условию.
3. Теперь вычислим процентное соотношение. Для этого количество чисел, делящихся на 5, разделим на общее количество чисел в последовательности и умножим результат на 100%.
Формула для расчета процента:$ (\frac{\text{количество подходящих чисел}}{\text{общее количество чисел}}) \times 100\% $
Подставляем наши значения:$ (\frac{2}{8}) \times 100\% = \frac{1}{4} \times 100\% = 0.25 \times 100\% = 25\% $
Следовательно, числа, делящиеся на 5, составляют 25% от всех чисел в данной последовательности.
