Answer 1

$m = - 72.35$

$n = - 27.65$

$m + n = - 72 . 35 + ( - 27.65) = - 72.35 - 27.65 = - (72.35 + 27.65) = - 100$

$m = - 27 \frac{13}{18}$

$n = - 22 \frac{5}{18}$

$m + n = - 27 \frac{13}{18} + ( - 22 \frac{5}{18} ) = - 27 \frac{13}{18} - 22 \frac{5}{18} = - (27 \frac{13}{18} + 22 \frac{5}{18} ) = - (27 + \frac{13}{18} + 22 + \frac{5}{18} ) = - (49 + \frac{13 + 5}{18} ) = - (49 + \frac{18}{18} ) = - (49 + 1) = - 50$

$m = - 22.625$

$n = - 2 \frac{3}{8}$

$m + n = - 22.625 + ( - 2 \frac{3}{8} ) = - 22.625 - 2 \frac{3}{8} = - (22.625 + 2 \frac{3}{8} ) = - (22 + 0.625 + 2 + \frac{3}{8} ) = - (24 + \frac{625}{1000} + \frac{3}{8} ) = - (24 + \frac{625÷125}{1000÷125} + \frac{3}{8} ) = - (24 + \frac{5}{8} + \frac{3}{8} ) = - (24 + \frac{5 + 3}{8} ) = - (24 + \frac{8}{8} ) = - (24 + 1) = - 25$

$m = - 0.9375$

$n = - \frac{1}{4}$

$m + n = - 0.9375 + ( - \frac{1}{4} ) = - 0.9375 - \frac{1}{4} = - (0.9375 + \frac{1}{4} ) = - (0.9375 + \frac{1 \times 25}{4 \times 25} ) = - (0.9375 + \frac{25}{100} ) = - (0.9375 + 0.25) = - (0.9375 + 0.2500) = - 1.1875$
