Решение. №25 (с. 32)
Решение 2. №25 (с. 32)
Для решения этой задачи нам даны два уравнения: $7x = 10$ и $49y = 25$. Необходимо найти значение выражения $\frac{25x}{28y} + 1,5$.
Сначала преобразуем искомое выражение. Дробь $\frac{25x}{28y}$ можно записать как произведение коэффициента и отношения переменных:
$\frac{25x}{28y} = \frac{25}{28} \cdot \frac{x}{y}$
Таким образом, всё выражение примет вид:
$\frac{25}{28} \cdot \frac{x}{y} + 1,5$
Теперь найдем значение отношения $\frac{x}{y}$, используя данные уравнения.
Из первого уравнения $7x = 10$ выразим переменную $x$:
$x = \frac{10}{7}$
Из второго уравнения $49y = 25$ выразим переменную $y$:
$y = \frac{25}{49}$
Теперь мы можем найти значение дроби $\frac{x}{y}$, подставив полученные выражения:
$\frac{x}{y} = \frac{\frac{10}{7}}{\frac{25}{49}}$
Для деления одной дроби на другую, мы умножаем первую дробь на дробь, обратную второй:
$\frac{x}{y} = \frac{10}{7} \cdot \frac{49}{25} = \frac{10 \cdot 49}{7 \cdot 25}$
Проведем сокращение. Сократим 49 и 7 на 7, а 10 и 25 на 5:
$\frac{10 \cdot 49}{7 \cdot 25} = \frac{(2 \cdot 5) \cdot (7 \cdot 7)}{7 \cdot (5 \cdot 5)} = \frac{2 \cdot 7}{5} = \frac{14}{5}$
Теперь, когда мы нашли значение $\frac{x}{y} = \frac{14}{5}$, подставим его обратно в преобразованное выражение:
$\frac{25}{28} \cdot \frac{14}{5} + 1,5$
Вычислим значение произведения дробей, выполнив сокращение:
$\frac{25 \cdot 14}{28 \cdot 5} = \frac{(5 \cdot 5) \cdot 14}{(2 \cdot 14) \cdot 5} = \frac{5}{2}$
Переведем дробь $\frac{5}{2}$ в десятичный формат: $\frac{5}{2} = 2,5$.
Наконец, выполним последнее действие — сложение:
$2,5 + 1,5 = 4$
