Обозначим все масло в бочке - 1
3/10 масла в первый бидон
1/2 масла во второй
3/10+1/2=3/10+5/10=8/10=4/5 масла в первый и второй
1-4/5=1/5 масла в третий
3/10-1/5=1/10 масла разница между первым и третьим, а это 6 литров
6:1/10=60литров масла было в бочке

madishecka12: а откуда 5,18/10?
miron2077: сбился при записи, исправлю сейчас, обнови
madishecka12: здесь напиши ничего
miron2077: 3/10+1/2=3/10+5/10=8/10=4/5, просто отвлекся и пропусти 0 и =
madishecka12: спс большое
