Question

Среди этих дробей найди лишнее .почему? 3/6 9/18 5/10 3/5 4/8 1/2​

Answer 1

Если числитель и знаменатель дроби одновременно разделить или умножить на одно и то же число, то значение дроби не изменится.

3/6 = 1/2 - сократили на 3

9/18 = 1/2 - сократили на 9

5/10 = 1/2 - сократили на 5

3/5 - несократимая дробь, потому что 3 и 5 - простые числа

4/8 = 1/2 - сократили на 4

1/2 - несократимая дробь

Ответ: 3/5, потому что не 1/2.

Answer 2

Ответ:

3/5

Пошаговое объяснение:

потому что при сокращении всех остальных дробей получается 1/2

Answer 3

Finding the Odd Fraction

To find the odd fraction among the given fractions, let's examine each fraction and determine which one does not belong.

The given fractions are: - 3/6 - 9/18 - 5/10 - 3/5 - 4/8 - 1/2

To determine the odd fraction, we can simplify each fraction and compare them:

1. 3/6: This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3. Simplifying, we get 1/2.

2. 9/18: This fraction can also be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 9. Simplifying, we get 1/2.

3. 5/10: This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5. Simplifying, we get 1/2.

4. 3/5: This fraction cannot be simplified further.

5. 4/8: This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4. Simplifying, we get 1/2.

6. 1/2: This fraction cannot be simplified further.

By comparing the simplified fractions, we can see that 3/5 is the odd fraction among the given fractions. The other fractions, 1/2, are equivalent to each other.

Therefore, the odd fraction is 3/5.
