1. 2,6 × 0,0 =2. 5/6 – 1/3 =3. 9/10-2/5=

1).

$2.6 times 0.0 = 2.6 times 0 = 0$

2).

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

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

$frac{5}{6} - frac{2}{6} = frac{5 - 2}{6} = frac{3}{6} = frac{1}{2} = frac{1 times 5}{2 times 5} = frac{5}{10} = 0.5$

3).

$frac{9}{10} - frac{2}{5} =$

$0.9 - frac{2 times 2}{5 times 2} =$

$0.9 - frac{4}{10} = 0.9 - 0.4 = 0.5$
