Answer 1

Salutare!

fractie ireductibila = fractie care nu se mai poate simplifica

" / " = semn de fractie ; "supra"

a)

1 : 3 = 1/3

1 : 1/3 = 1 × 3/1 = 3/1

1 : 4/8 = 1 × 8/4 = 8/4⁽⁴ = 2/1

b)

3 : 1 = 3/1

1/3 : 1 = 1/3 × 1/1 = 1/3

4/8 : 1 = 4/8 × 1/1 = 4/8⁽⁴ = 1/2

Answer 2

Răspuns:

a)  1 : 3

    1 = $\frac{1}{1}$    

    3 = $\frac{3}{1}$

    $\frac{1}{1} : \frac{3}{1} = \frac{1}{1} * \frac{1}{3} =\frac{1}{3}$

     $1 : \frac{1}{3} \\\\1 = \frac{1}{1}\\\\\frac{1}{1} : \frac{1}{3} =\frac{1}{1} * \frac{3}{1} = \frac{3}{1}$

     $1 : \frac{4}{8} \\\\1 = \frac{1}{1} \\\\\frac{1}{1} : \frac{4}{8} = \frac{1}{1} *\frac{8}{4} = \frac{8}{4} = \frac{2}{1}$

   

b)

      $3 : 1 \\\\3 = \frac{3}{1}\\\\1 = \frac{1}{1} \\\\\frac{3}{1} : \frac{1}{1} = \frac{3}{1} * \frac{1}{1} = \frac{3}{1}$

      sau:

      3 : 1 = 3

      3 = $\frac{3}{1}$

      $\frac{1}{3} : 1 \\\\1 = \frac{1}{1} \\\\\frac{1}{3} : \frac{1}{1} = \frac{1}{3} * \frac{1}{1} = \frac{1}{3}$

       $\frac{4}{8} : 1 \\ \\1 = \frac{1}{1} \\\\\frac{4}{8} : \frac{1}{1} = \frac{4}{8} * \frac{1}{1} = \frac{4}{8} = \frac{1}{2}$
