Question

Fractions can be added and subtracted only if they are _____ fractions.

Answer 1

Hello.

Fractions can be added and subtracted only if they are like fractions.

Example:

$\mathrm{\displaystyle\frac{5}{9} -\frac{4}{9} =\frac{1}{9}}$

We can subtract these fractions because they are like fractions (they have the same denominator)

Another Example:

$\mathrm{\displaystyle\frac{4}{9} +\frac{3}{9} =\frac{7}{9}}$

We can add these fractions because they are like fractions.

Therefore, the answer is "like"

I hope it helps.

Have a nice day.
