Пошаговое объяснение:

7 1/3+2 4/27= =9  (9+4)/27 = 9  13/27;

3 11/18 + 1 1/12=   4  (22+3)/36 = 4  25/36;

5 5/6 - 2 3/4=   3  (10-9)/12=3  1/12;

2 19/36- 7/9= 2    (19-28)/36  = 1  (36+19-28)/36 = 1  27/36 = 1  9/13;

2 2/9 - 1 4/9=​  1  (2-4)/9 = (9+2-4)/9=7/9.

Answer 3

Let's solve each of these arithmetic problems step by step:

1. $7 \frac{1}{3} + 2 \frac{4}{27}$

To add these mixed numbers, you can first find a common denominator for the fractions:

$\frac{7 \cdot 3}{3} + \frac{2 \cdot 27}{27} = \frac{21}{3} + \frac{54}{27}$

Now, simplify each fraction:

$\frac{21}{3} = 7$ and $\frac{54}{27} = 2$

So, $7 + 2 = 9$

2. $3 \frac{11}{18} + 1 \frac{1}{12}$

Again, find a common denominator for the fractions:

$\frac{3 \cdot 18}{18} + \frac{1 \cdot 12}{12} = \frac{54}{18} + \frac{12}{12}$

Simplify each fraction:

$\frac{54}{18} = 3$ and $\frac{12}{12} = 1$

So, $3 + 1 = 4$

3. $5 \frac{5}{6} - 2 \frac{3}{4}$

Find a common denominator for the fractions:

$\frac{5 \cdot 6}{6} - \frac{2 \cdot 4}{4} = \frac{30}{6} - \frac{8}{4}$

Simplify each fraction:

$\frac{30}{6} = 5$ and $\frac{8}{4} = 2$

So, $5 - 2 = 3$

4. $2 \frac{19}{36} - \frac{7}{9}$

Again, find a common denominator for the fractions:

$\frac{2 \cdot 36}{36} - \frac{7 \cdot 4}{9 \cdot 4} = \frac{72}{36} - \frac{28}{36}$

Simplify each fraction:

$\frac{72}{36} = 2$ and $\frac{28}{36} = \frac{7}{9}$

So, $2 - \frac{7}{9}$ can be simplified by finding a common denominator for 2 and $\frac{7}{9}$, which is 9:

$\frac{2 \cdot 9}{9} - \frac{7}{9} = \frac{18}{9} - \frac{7}{9}$

Now, subtract the fractions:

$\frac{18}{9} - \frac{7}{9} = \frac{11}{9}$

5. $2 \frac{2}{9} - 1 \frac{4}{9}$
