Answer 1

Путь = 4*а
засеяли 0,01*b
2/3 девочки

Answer 2

Problem 1: Автобус проехал а км, что составило 1/4 пути. Чему равен весь путь?

To find the total distance traveled by the bus, we need to determine the value of "a" in the given equation. According to the problem, the bus has traveled "a" kilometers, which is 1/4 of the total distance.

Let's solve this problem step by step:

1. Let's assume the total distance traveled by the bus is "x" kilometers. 2. According to the problem, "a" kilometers is 1/4 of the total distance, so we can write the equation as: a = (1/4) * x. 3. To find the value of "x," we can multiply both sides of the equation by 4: 4a = x.

Therefore, the total distance traveled by the bus is 4a kilometers.

Answer: The total distance traveled by the bus is 4a kilometers.

Problem 2: Площадь поля b м. Горохом засеяли 1% поля. Сколько квадратных метров засеяли горохом?

To find the number of square meters of the field that were sown with peas, we need to calculate 1% of the total area of the field.

Let's solve this problem step by step:

1. The problem states that the area of the field is "b" square meters. 2. We need to find 1% of the total area, which can be calculated by multiplying the total area by 1/100: (1/100) * b.

Therefore, the number of square meters sown with peas is (1/100) * b.

Answer: The number of square meters sown with peas is (1/100) * b.

Problem 3: В классе с учениками. Из них 1/3 составляют мальчики. Сколько девочек в классе?

To find the number of girls in the class, we need to calculate 2/3 of the total number of students, as 1/3 of the students are boys.

Let's solve this problem step by step:

1. The problem states that there are "n" students in the class. 2. We need to find the number of girls, which is 2/3 of the total number of students. This can be calculated by multiplying the total number of students by 2/3: (2/3) * n.

Therefore, the number of girls in the class is (2/3) * n.

Answer: The number of girls in the class is (2/3) * n.
