Answer 1

Ответ:29/6 тоесть 4 5/6

Пошаговое объяснение:

Answer 2

2 - 1 5/9 = 1 9/9 - 1 5/9 = 4/9
7 - 2 11/18 = 6 18/18 - 2 11/18 = 4 7/18
4/9 + 4 7/18 = 8/18 + 4 7/18 = 4 15/18 = 4 5/6

Answer 3

To add these two mixed numbers, we first need to convert them into improper fractions.

For the first mixed number, 2-1 5/9, we can convert it as follows:

2-1 5/9 = 2 - (1*9 + 5)/9 = 2 - 14/9

For the second mixed number, 7-2 11/18, we can convert it as follows:

7-2 11/18 = 7 - (2*18 + 11)/18 = 7 - 47/18

Now, we can add these two improper fractions:

(2 - 14/9) + (7 - 47/18)

To add these two fractions, we first need to find a common denominator. The smallest number that both 9 and 18 divide into evenly is 18. So, we can rewrite the fractions with a denominator of 18:

(218/18 - 14/9) + (718/18 - 47/18)

Simplifying this expression, we get:

(36/18 - 14/9) + (126/18 - 47/18)

Now, we can combine like terms:

2 - 28/9 + 7 - 47/18

Simplifying this expression further, we get:

9 - (28/9 + 47/18)

To add these two fractions, we first need to find a common denominator. The smallest number that both 9 and 18 divide into evenly is 18. So, we can rewrite the fractions with a denominator of 18:

9 - (2*28/18 + 47/18)

Simplifying this expression, we get:

9 - 103/18

Finally, we can write this as a mixed number:

8 1/18

Therefore, (2-1 5/9)+(7-2 11/18) = 8 1/18.
