The parts have to be EQUAL
Cutting a roti into two pieces does not make halves unless both pieces are the same size. A fraction only means something when the whole is split evenly.

Fractions, explained with pictures
Numbers for the pieces of a whole, not just for whole things.
In everyday life: Half a roti, a quarter of an hour, one third of a chocolate bar shared three ways.
The bottom number says how many pieces the whole was cut into
In 3/4, the 4 says the whole was cut into four equal parts, and the 3 says you have three of them. A bigger bottom number means SMALLER pieces — 1/8 is less than 1/4.
Different fractions can be the same amount
1/2, 2/4 and 4/8 all cover the same part of the whole. You cut more times, but each piece is smaller, so it evens out. These are equivalent fractions.
A worked example
Which is bigger, 1/3 or 1/5?
1/3
Both are one piece. But cutting something into 3 gives bigger pieces than cutting it into 5. Fewer cuts, bigger piece.
