Вопрос школьника по предмету Математика
у сільгосппідприємстві посіяли кукурудзу на площі 24,5 га, що в 1,4 разу більше, ніж площа, засіяна гречкою. Урожайніть гречки виявилась у 4 рази меншою, ніж урожайність кукурудзи. Скільки в сільгосппідприємстві зібрали гречки, якщо кукурудзи зібрали 99,96 т?
