Mixed number in simplest form

Question

11 5/8 + 5 2/3

Answer 1

Hi Adi,

You can add these mixed numbers in more than one way.

FIRST WAY: You can add the whole numbers first, then add the fractional parts (using a least common denominator).

SECOND WAY: You can convert both mixed numbers to improper fractions, find a common denominator, add the fractions, then simplify your solution.

Let's try it the first way:

11 + 5 is 16

Now lets add the fractional parts. The least common denominator will be 24:

5 = 15 2 = 16

8 24 3 24

Now add : 15 + 16 = 31

24 24 24

31 is equivalent to 1 7

24 24

The final sum will be 16 + 1 7 = 17 7

24 24

Hope this helps Adi. Please let me know if you have more questions or would like to schedule a session (online if you prefer).

Take care.
