Question

Привести к наименьшему общему знаменателю дроби

Answer 1

Общий знаменатель 2 дробей - это общее кратное их знаменателей.
Чтобы привести дробь к наименьшему общему знаменателю, надо:
1.Найти НОК знаменателей данных дробей
2.Найти дополн.множители для каждой из дробей разделив общий знаменатель на знаменатели данных дробей.
3.Умножить числитель и знаменатель каждой дроби на её дополнительный множитель.

Answer 2

Finding the Least Common Denominator (LCD) of Fractions

To find the least common denominator (LCD) of fractions, we need to determine the smallest number that is divisible by all the denominators involved. Once we have the LCD, we can convert the fractions to have the same denominator, making it easier to perform operations on them.

Let's take an example to illustrate the process. Suppose we have the fractions 1/6 and 1/2, and we want to find their least common denominator.

To find the LCD, we can follow these steps:

1. Identify the denominators of the fractions. In this case, the denominators are 6 and 2.

2. Determine the prime factors of each denominator. The prime factors of 6 are 2 and 3, while the prime factor of 2 is just 2.

3. Take the highest power of each prime factor that appears in any of the denominators. In this case, the highest power of 2 is 2^1, and the highest power of 3 is 3^1.

4. Multiply these highest powers together to get the LCD. In this case, the LCD is 2^1 * 3^1 = 6.

Now that we have the LCD, we can convert the fractions to have a common denominator of 6:

1/6 = (1 * 1)/6 = 1/6

1/2 = (1 * 3)/6 = 3/6

So, the fractions 1/6 and 1/2, when converted to have a common denominator of 6, become 1/6 and 3/6, respectively.

In summary, the least common denominator (LCD) of the fractions 1/6 and 1/2 is 6.
