Question

2 / 11 + 5 / 22 + 7 / 33​

Answer 1

Ответ:

$\frac{2}{11} + \frac{5}{22} + \frac{7}{33} = \frac{12}{66} + \frac{15}{66} + \frac{14}{66}$

Пошаговое объяснение:

Находим общий знаменатель для всех чисел. 66.

Знаменатель пишем 66, 66 делим на числитель, получаем число. На это число умножаем старый числитель и получаем новый числитель для новой дроби:

$\frac{2}{11} + \frac{5}{22} + \frac{7}{33} = \frac{12}{66} + \frac{15}{66} + \frac{14}{66}$

Answer 2

Ответ:

41/66

Пошаговое объяснение:

1) 2/11 + 5/22 = 2 × 2 × 5/22 = 9/22

2) 9/22 + 7/33 = 3 × 9 × 2 × 7/66 = 41/66

Answer 3

To add these fractions, you'll need to find a common denominator. In this case, the least common denominator is 66, which is the least common multiple of 11, 22, and 33. Once you have a common denominator, you can add the fractions together.

2/11 + 5/22 + 7/33

To make the denominators all equal to 66, you can do the following:

2/11 * 6/6 = 12/66 5/22 * 3/3 = 15/66 7/33 * 2/2 = 14/66

Now the fractions have a common denominator, so you can add them together:

12/66 + 15/66 + 14/66

Now, you can add the numerators:

(12 + 15 + 14) / 66 = 41/66

So, 2/11 + 5/22 + 7/33 = 41/66.
