CVita $1 \frac{1}{2}- \frac{2}{3}= \frac{3}{2}- \frac{2}{3}= \frac{9-4}{6}= \frac{5}{6}$
$1 \frac{1}{4}- \frac{1}{3}= \frac{5}{4}- \frac{1}{3}= \frac{15-4}{12}= \frac{11}{12}$
$1 \frac{1}{8}- \frac{1}{4}= \frac{9}{8}- \frac{1}{4}= \frac{9-2}{8}= \frac{7}{8}$
$1 \frac{2}{3}- \frac{5}{6}= \frac{5}{3}- \frac{5}{6}= \frac{10-5}{6}= \frac{5}{6}$
$2 \frac{3}{10}- \frac{4}{15}= \frac{23}{10}- \frac{4}{15}= \frac{69-8}{30}= \frac{61}{30}=2 \frac{1}{30}$
$3 \frac{1}{4}- \frac{5}{6}= \frac{13}{4}- \frac{5}{6}= \frac{39-10}{12} = \frac{29}{12}=2 \frac{5}{12}$
