Question

Как сокротить обыкновенную дробь?

Answer 1

Возьмём дробь  $\frac{2}{12}$
Мы можем сократить и числитель и знаменатель на 2. Получиться: $\frac{1}{6}$.
Сокращение - это когда ты можешь разделить и знаменатель и числитель на одно и тоже число, будь то 3, 4, 5, 55, 190 и т.д.
На всякий случай еще покажу:
$\frac{20}{60}$ = $\frac{20 (:20)}{60(:20)}$ = $\frac{1}{3}$
Не всегда сокращается полностью:
$\frac{14}{82} = \frac{14(:2)}{82(:2)} = \frac{7}{41}$

How to Simplify a Fraction

To simplify an ordinary fraction, you can follow these steps:

1. Find the Greatest Common Divisor (GCD): - The first step in simplifying a fraction is to find the greatest common divisor (GCD) of the numerator and the denominator. The GCD is the largest positive integer that divides each of the numbers without leaving a remainder.

Source: 2. Divide by the GCD: - Once you have found the GCD, divide both the numerator and the denominator of the fraction by the GCD. This will give you the simplified form of the fraction.

Example Calculation

Let's take an example to illustrate the process:

Given fraction: 36/12

1. Find the GCD: - The GCD of 36 and 12 is 12.

2. Divide by the GCD: - Dividing both the numerator and the denominator by 12 gives us the simplified form: - 36 ÷ 12 = 3 - 12 ÷ 12 = 1 - So, the simplified form of 36/12 is 3/1, which is equal to 3.
