Аравны хэсгээр тоймлоорой гэхээр 2.91-ийг ойролцоогоор 2.9 гэж тооцож болно. Энэ тоог аравтын системд хамгийн ойрхон бүтэн тоо болох 3-ын дэргэдээ байрлуулдаг тул ойролцоогоор 3 гэж хэлж болно. Тиймээс, 2.91-ийг тоймлоход 3 гэж хэлэх нь хамгийн зөв тооцоо юм. Хэрвээ энэ тоог шалгах шаардлагатай бол 2.9 буюу 2.91-ийг тоймлоход 2.9-ийг сургаснаар тооны градуудын барагцаа илрэх болно. Тэгэхээр 2.91-ийг тодорхойлохдоо, хаашаа ч бахархаж зальж байгаа бэ гэдгийг анхаарах хэрэгтэй!
