Question

Cum se impart,adun,scad,inmultesc fractiile(clasa 6)

Answer 1

impart : prima fractie se scrie normal si se inmulteste cu cea de a doua rasturnata
Adun si scad : daca au acelasi numitor se aduna sau scad  numaratorii si numitorii se scriu la fel ..
Inmultire : se inmulteste numaratorul primei fractii cu al doile si la fel si numitorii ( se pot face si simplificari pe diagonala )
