13/4 + 1 3/4 = ? i need to show all work. you.

1 3/4 + 1 3/4 = 2 + 1 + 1/2 = 3 1/2 or 3.5
Explanation :
1 and 1 add up to two
Let's take 3/4 as (2/4 + 1/4)
2 (2/4) add up to make 1
1/4 and 1/4 left .. Which added gives 2/4 or (1/2)
How u wud answer this is :
1 3/4 + 1 3/4
= 1 + 1 + 3/4 + 3/4
= 2 + 6/4
= 2 + 3/2 (6/4 simplified)
{Taking the LCM of 2}
= (2/1)×2 + 3/2
= 4/2 + 3/2
= 7/2
= 3 1/2
