I made up for in order to be equal and to be sure I'll explain it so can you tell me if I'm wrong. Imagine we have three chocolate bars identical to each other in weight and dimensions. Mario eats 5/8 of its tablet. Anna eats 5/4 of its tablet. John eats 7/3 of its tablet. As is evident, Mario, Anna and John ate the same amount of chocolate. then, generalizing, we can say that two or more fractions are eqivalenti between them when, despite being spelled differently, represent the same value.
