4*. 10/2 - 4/2 - 3/2=

5*. 12/6 - 4/5 - 7/2=

6*. 11/2 - 2/4=

7*. 18/4 + 3/2=

8*. 9/4 + 5/3=

9*. 3/6 + 2/4=​

Answer 1

Explicación paso a paso:

1*. 1/3+2/3+4/3

$\frac{1}{3} + \frac{2}{3} + \frac{4}{3} = \frac{1 + 2 + 4}{3} = \frac{7}{3}$

2*. 4/5+5/5+3/5

De igual forma que el anterior:

= 12/5

3*. 12/8 - 6/8 - 3/8

De manera similar a las anteriores pero restando:

= ⅜

4*. 10/2 - 4/2 - 3/2

Similar al anterior:

= 3/2

5*. 12/6* - 4/5 - 7/2

*12/6 = 2

= 2 - ⅘ - 7/2

$2 - \frac{4}{5} - \frac{7}{2} \\ = 2( \frac{10}{10} ) - \frac{4}{5}( \frac{2}{2} ) - \frac{7}{2}( \frac{5}{5} ) \\ = \frac{20}{10} - \frac{8}{10} - \frac{35}{10} = \frac{20 - 8 - 35}{10} = - \frac{23}{10}$

6*. 11/2 - 2/4*

*2/4 = ½

= 11/2 - ½

$\frac{11}{2} - \frac{1}{2} = \frac{11 - 1}{2} = \frac{10}{2} = 5$

7*. 18/4* + 3/2

*18/4 = 9/2

= 9/2 + 3/2 = 12/2 = 6

8*. 9/4 + 5/3

$\frac{9}{4} + \frac{5}{3} \\ = \frac{9}{4}( \frac{3}{3} ) + \frac{5}{3}( \frac{4}{4} ) = \frac{27}{12} + \frac{20}{12} = \frac{27 + 20}{12} = \frac{47}{12}$

9*. 3/6 + 2/4 = ½ + ½ = 2/2 = 1
