Hello! That's an excellent question!


  1. Make sure the bottom numbers (the denominators) are the same.
  2. Add the top numbers (the numerators), put that answer over the denominator.
  3. Step 3: Simplify the fraction (if needed)


In this instance the answer would be 7/11!


I hope that helps!

3/11+4/11=7/11 You can just sum up the numerators since the denumerators are the same.

The denominator stays the same as they're both 11, you add the top (3+4) which equals 7, the final answer is 7/11.

Read the question out loud - three elevenths add four elevenths.

Draw a rectangle with eleven sections. Colour in three elevenths. Now colour in another four elevenths. How many elevenths are coloured in?

Now how do you write the answer?

Look at the answer relative to the numbers to see what happens to the numerators and denominators.

Do you think you can do future questions without the need to draw rectangles?

We would add the numerators (the top numbers of both fractions) together: 3 + 4 = 7.

When adding and subtracting fractions, we keep the denominators (the bottom numbers of both fractions) the same, so this stays as 11.

This makes our answer 7/11.

If the denominators (bottom numbers) are the same, as they are in the question, you can simply add the numerators (top numbers).

So, your answer would be 7/11.


If the denominators were different, you would have to convert them to the same number, then add the numerators, then simplify if possible.


Hope this helps!

3/11 + 4/11= 3+4/11 = 7/11

As the denominator is same in both the fraction, you don't need to take LCM. We can straight away add both the numerators and then write the denominator.


=3+4/11

=7/11
