Question

Найдите разность дробей: 4/5-3/10-2/13

Answer 1

$frac{4}{5} - frac{3}{10} - frac{2}{13} = frac{8}{10} - frac{3}{10} - frac{2}{13} = frac{5}{10} - frac{2}{13} = frac{65}{130} - frac{20}{130} = frac{45}{130} = frac{9}{26}$

Answer 2

1) 4/5 - 3/10 = 8/10 - 3/10 = 5/10 = 1/2
2) 1/2 - 2/13 = 13/26 - 4/26 = 9/26
Ответ 9/26
