Question

16supra36 +2 7supra21-6supra36-7supra36

Answer 1

Răspuns:

    $\frac{29}{12}$

Explicație pas cu pas:

    $\frac{16}{36} + 2\frac{7}{21} - \frac{6}{36} -\frac{7}{36} =$

    $\frac{16}{36} +\frac{49}{21} -\frac{6}{36} -\frac{7}{36} =$

    $\frac{16*21}{36*21} +\frac{36*49}{36*21} -\frac{21*6}{21*36} -\frac{7*21}{36*21} =$

    $\frac{336}{756} +\frac{1764}{756} -\frac{126}{756} -\frac{147}{756} =$

    $\frac{1827/3}{756/3}$$=$

    $\frac{609/3}{252/3} =$

    $\frac{203/7}{84/7}$ = $\frac{29}{12} =$ 2,41(6)
