Question

а) 3 1/3-1/2
б) 5 1/4-2/3
в) 2 2/5-7/10
г) 4 1/6-2/3

Answer 1

$3 frac{1}{3} - frac{1}{2} = 3 frac{2 - 3}{6} = 2 frac{5}{6}$

$5 frac{1}{4} - frac{2}{3} = 5 frac{3 - 8}{12} = 4 frac{5}{12}$

$2 frac{2}{5} - frac{7}{10} = 2 frac{4 - 7}{10} = 1 frac{3}{10}$

$4 frac{1}{6} - frac{2}{3} = 4 frac{1 - 4}{6} = 3 frac{3}{6} = 3 frac{1}{2}$
