Question

calculati media aritmetica a nr 0,75 si 1 supra 6

Answer 1

$m_{a}=(0.75 + \frac{1}{6} ) \div 2 \\ \\ = ( \frac{75}{100} + \frac{1}{6} ) \div 2 \\ \\ = ( \frac{3}{4} + \frac{1}{6} ) \div 2 \\ \\ = ( \frac{9}{12} + \frac{2}{12} ) \div 2 \\ \\ = \frac{9 + 2}{12} \div 2 \\ \\ = \frac{11}{12} \times \frac{1}{2} \\ \\ = \frac{11 \times 1}{12 \times 2} \\ \\ = \frac{11}{24}$
