Question

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

Answer 1

C, because it should be same denominators

Answer 2

Hello.

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

Example:

`\mathrm{\displaystyle(5)/(9) -(4)/(9) =(1)/(9)}`

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

Another Example:

`\mathrm{\displaystyle(4)/(9) +(3)/(9) =(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.
