Answer 1

Respuesta:

5/6 + 1/12 = 10/12 +1/12 = 11/12

1/4 + 3/8 = 2/8 + 3/8 = 5/8

1/7 + 8/21 = 3/21 + 8/21 = 11/21

3/5 + 1/9 = 27/45 + 5/45 = 32/45

2/3 + 1/9 = 6/9 + 1/9 = 7/9

1/5 + 4/3 = 3/15 + 20/15 = 23/15

5/7 + 1/2 = 10/14 + 7/14 = 17/14

4/5 - 1/7 = 28/35 - 5/35 = 23/35

3/4 - 3/8 = 6/8 - 3/8 = 3/8

2/3 - 1/9 = 6/9 - 1/9 = 5/9

3/5 - 1/9 = 27/45 - 5/45 = 22/45

5/6 - 1/12 = 10/12 - 1/12 = 9/12

4/5 - 1/3 = 12/15 - 5/15 = 7/15

1/7 - 2/21 = 3/21 - 2/21 = 1/21

5/7 - 1/2 = 10/14 - 7/14 = 3/14

Answer 2

Respuesta:

Pliss me tome el tiempo de hacerlo dame una corona :'3

Explicación paso a paso:

Suma:

1.

$\frac{5}{6} + \frac{1}{12} = \frac{60}{72} + \frac{6}{72} = \frac{66}{72}$

2.

$\frac{1}{7} + \frac{8}{21} = \frac{21}{147} + \frac{56}{147} = \frac{77}{147}$

3.

$\frac{4}{5} + \frac{1}{7} = \frac{28}{35} + \frac{5}{35} = \frac{33}{35}$

4.

$\frac{2}{3} + \frac{1}{9} = \frac{18}{27} + \frac{3}{27} = \frac{21}{27}$

5.

$\frac{1}{5} + \frac{4}{3} = \frac{3}{15} + \frac{20}{15} = \frac{23}{15}$

6.

$\frac{5}{7} + \frac{1}{2} = \frac{10}{14} + \frac{7}{14} = \frac{17}{14}$

7.

$\frac{1}{4} + \frac{3}{8} = \frac{8}{32} + \frac{12}{32} = \frac{20}{32}$

8.

$\frac{3}{5} + \frac{1}{9} = \frac{27}{45} + \frac{5}{45} = \frac{32}{45}$

Resta:

1.

$\frac{4}{5} - \frac{1}{7} = \frac{28}{35} - \frac{5}{35} = \frac{23}{35}$

2.

$\frac{2}{3} - \frac{1}{9} = \frac{18}{27} - \frac{3}{27} = \frac{15}{27}$

3.

$\frac{5}{6} - \frac{1}{12} = \frac{60}{72} - \frac{6}{72} = \frac{54}{72}$

4.

$\frac{1}{7} - \frac{2}{21} = \frac{21}{147} - \frac{14}{147} = \frac{7}{147}$

5.

$\frac{3}{4} - \frac{3}{8} = \frac{24}{32} - \frac{12}{32} = \frac{12}{32}$

6.

$\frac{3}{5} - \frac{1}{9} = \frac{27}{45} - \frac{5}{45} = \frac{22}{45}$

7.

$\frac{4}{5} - \frac{1}{3} = \frac{12}{15} - \frac{5}{15} = \frac{7}{15}$

8.

$\frac{5}{7} - \frac{1}{2} = \frac{10}{14} - \frac{7}{14} = \frac{3}{14}$
