Odpowiedź:
( 1/4+ 1/12)· 6= ( 3/12+ 1/12)· 6= 4/12·6= 24/12= 2
2 2/5· 2= 12/5·2= 24/5= 4 4/5
Szczegółowe wyjaśnienie:
[tex]2 \frac{2}{5} (( \frac{1}{4} + \frac{1}{12} ) \times 6) = \\ 2 \frac{2}{5} (( \frac{3}{12} + \frac{1}{12} ) \times 6) = \\ 2 \frac{2}{5} ( \frac{4}{12} \times 6) = \\ \frac{12}{5} \times 2 = \\ \frac{24}{5} = 4 \frac{4}{5} [/tex]
