9 9/10 + 2 3/5 =

Answer 1

To add these fractions, we can first convert the mixed numbers into improper fractions.

9 9/10 can be written as (9 * 10 + 9)/10 = 99/10.

2 3/5 can be written as (2 * 5 + 3)/5 = 13/5.

Now, we can add the fractions: 99/10 + 13/5.

To add these fractions, we need to find a common denominator, which will be 10 in this case.

Since 10 is already the denominator for 99/10, we don't need to change it.

To make 13/5 have a denominator of 10, we need to multiply the numerator and denominator by 2: (13 * 2)/(5 * 2) = 26/10.

Now, we can add the fractions: 99/10 + 26/10 = (99 + 26)/10 = 125/10.

The final answer is 125/10, which can be simplified further as 12 5/10 or 12 1/2.
