Question

Сравните дроби 3/7и1/3 , 4/19 и 2/11.

Answer 1

Приведем к общему знаменателю и сравним числители:

3/7 = 9/21

1/3 = 7/21

3/7 > 1/3

4/19 = 44/209

2/11 = 38/209

4/19 > 2/11

Answer 2

Приводим к общему знаменателю

и сравниваем

3/7и1/3 - 9/21>7/21

4/19 и 2/11 - 44/209>38/209

Answer 3

To compare fractions, we need to convert them to a common denominator. We can use the least common multiple (LCM) of the denominators as the common denominator.

For 3/7 and 1/3, the LCM of 7 and 3 is 21, so we can convert the fractions as follows:

3/7 = 9/21 (multiply numerator and denominator by 3) 1/3 = 7/21 (multiply numerator and denominator by 7)

Now we can see that:

9/21 > 7/21

Therefore, 3/7 is greater than 1/3.

For 4/19 and 2/11, the LCM of 19 and 11 is 209, so we can convert the fractions as follows:

4/19 = 22/209 (multiply numerator and denominator by 11) 2/11 = 38/209 (multiply numerator and denominator by 19)

Now we can see that:

22/209 < 38/209

Therefore, 4/19 is less than 2/11.

So the final comparison is:

3/7 > 1/3 and 4/19 < 2/11.
