Answer 2

Ответ:

a)<; b)>; c)=; d)тут непонятно, но насколько я понимаю <

Пошаговое объяснение:

при одинаковом числителе чем меньше знаменатель тем больше число, при одинаковом знаменателе смотрим какой числитель больше. если знаменатель и числитель разные, то приводим к общему знаменателю(в данных случаях умножаем на 2 дробь с меньшим знаменателем)

Answer 3

Comparison of Fractions

Let's compare the given fractions:

a) 4/19 + 4/5

To add these fractions, we need to find a common denominator. The least common multiple (LCM) of 19 and 5 is 95. So, we can rewrite the fractions with the common denominator:

4/19 + 4/5 = (4 * 5)/(19 * 5) + (4 * 19)/(5 * 19) = 20/95 + 76/95 = (20 + 76)/95 = 96/95

b) 8/11 + 7/11

Since the denominators are the same, we can simply add the numerators:

8/11 + 7/11 = (8 + 7)/11 = 15/11

c) 2/15 + 4/30

To add these fractions, we need to find a common denominator. The LCM of 15 and 30 is 30. So, we can rewrite the fractions with the common denominator:

2/15 + 4/30 = (2 * 2)/(15 * 2) + (4 * 1)/(30 * 1) = 4/30 + 4/30 = 8/30

d) 1/14 + 1 + 3/7

To add these fractions, we need to convert the mixed number into an improper fraction.

1 + 3/7 = (1 * 7 + 3)/7 = 10/7

Now, we can find a common denominator for 14 and 7, which is 14. So, we can rewrite the fractions with the common denominator:

1/14 + 10/7 = (1 * 1)/(14 * 1) + (10 * 2)/(7 * 2) = 1/14 + 20/14 = 21/14

To summarize:

a) 4/19 + 4/5 = 96/95 b) 8/11 + 7/11 = 15/11 c) 2/15 + 4/30 = 8/30 d) 1/14 + 1 + 3/7 = 21/14
