13/8 + 5/4= can you show me how to get the answer?

The 5/4 equals to 1 1/4. Convert the 1/4 to eighths (1/8 btw) You multiply the denominator of the fraction to 8, so 4*2 equals 8 and you do the same thing to the 1, the numerator. So 1/4 should be equal to 2/8. Then, 5/4 should equal this = 1 2/8
For 1 3/8 you would add that with 1 2/8. Adding those two whole numbers 1 and 1 it equals two obviously. 3/8 + 2/8 equals 5/8. In the end it would equal 2 5/8 for the answer if I'm not correct.
