Автор ответа: Виамлер

10/15+6/15-1/15=15/15=1
вроде так как то ( в общем подводим к общему знаменателю и все)

Автор ответа: CioOrAn

$frac{2}{3} +frac{2}{5} -frac{1}{15}$ Приводим к общему знаменателю. К первой дроби 5
Ко второй дроби 3, а к последней 1
$frac{10}{15} +frac{6}{15} -frac{1}{15}$ И равно все это 1
