Выполните действие:5/12-2/9= 5/9+3/4=Помогите)))

Answer 1

$\frac{5}{12}$ - $\frac{2}{9}$ = $\frac{5 * 3}{12 * 3}$ - $\frac{2 * 4}{9 * 4}$ = $\frac{15}{36}$ - $\frac{8}{36}$ = $\frac{7}{36}$

$\frac{5}{9}$ + $\frac{3}{4}$ = $\frac{5 * 4}{9 * 4}$ + $\frac{3 * 9}{4 * 9}$ = $\frac{20}{36}$ + $\frac{27}{36}$ = $\frac{47}{36}$ = 1 $\frac{11}{36}$  

Answer 2

Calculation

To solve the given expression, we'll perform the following steps:

1. Subtract 2/9 from 5/12. 2. Add the result to 5/9. 3. Add 3/4 to the previous result.

Let's calculate step by step:

1. Subtract 2/9 from 5/12: - 5/12 - 2/9 = (35/36) - (32/36) = 3/36 = 1/12.

2. Add 5/9 to the result: - 1/12 + 5/9 = (1/12) + (20/36) = 32/36 = 8/9.

3. Add 3/4 to the previous result: - 8/9 + 3/4 = (32/36) + (27/36) = 59/36 = 1 23/36.

So, the final result of the given expression 5/12 - 2/9 + 5/9 + 3/4 is 1 23/36.
