Question

вычислите:
$24 \ \frac{2}{39} - 6 \ \frac{5}{13}$
$14\ \frac{1}{12} - 1 \ \frac{1}{18}$
$13 \ \frac{1}{18} - 10 \ \frac{1}{12}$
​

Answer 1

$24 \frac{2}{39} - 6 \frac{5}{13} = 23 \frac{41}{39} - 6 \frac{15}{39} = \\ = 17 \frac{26}{39} = 17 \frac{2}{3}$

°

$14 \frac{1}{12} - 1 \frac{1}{18} = 14 \frac{3}{36} - 1 \frac{2}{36} = 13 \frac{1}{36}$

°

$13 \frac{1}{18} - 10 \frac{1}{12} = 12 \frac{38}{36} - 10 \frac{3}{36} = \\ = 2 \frac{35}{36}$
