Hamdan says that when you add fractions with the same denominator, you can add the numerators and keep the same denominator. Is

Elina [12.6K]

Answer:

Yes, Hamdan is correct.

Step-by-step explanation:

Let the two fractions are q/r and s/r.

Here, the denominator is same for both the fractions.

So, as we add them, add the numerators and the denominators remains same.

$\frac{q}{r}+\frac{s}{r}\\\\=\frac{q + s}{r}$

For example

$\frac{3}{5}+\frac{4}{5}\\\\=\frac{3 + 4}{5}\\\\=\frac{7}{5}$

So, Hamdan is correct.
