Answer: 45/10

Step-by-step explanation:

We want to add

11/5 + 23/10

The first step is to find the lowest common multiple, LCM of the denominators. The LCM of 5 and 10 is 10. We would divide the LCM by each denominator and multiply each numerator by the results. The common denominator of the final fraction would be the LCM. We have

For the first fraction,

10/5 = 2

2 x 11 = 22

For the second fraction,

10/10 = 1

1 x 23 = 23

Thus, the final fraction would be

(22 + 23)/10

= 45/10
