Question

find the sum of -4 whole 5/6 and -7 whole 3/4​

Answer 1

$\: \: \: \: \: ( - 4 \frac{5}{6}) + ( - 7 \frac{3}{4} ) \\ = ( \frac{ - 24 + 5}{6} ) + ( \frac{ - 28 + 3}{4} ) \\ = ( \frac{ - 19}{6} ) + ( \frac{ - 25}{4}) \\ = - \frac{19}{6} - \frac{25}{4} = - ( \frac{19}{6} + \frac{25}{4} ) \\ = - ( \frac{19 \times 4 + 25 \times 6}{6 \times 4} ) \\ = - ( \frac{76 + 150}{24} ) = - \frac{226}{24} \\ = - \frac{113}{12}$
