Answer 2

Step-by-step explanation:

let the number that should be added be x

then ,

-13/4 + - 3/8 + x = 1

lcm of 4 and 8 is 8

multiply 2/2 to -13/8 to get denominators same and 1/1 to

-3/8

-26/8 - 3/8 +x = 1

-29/8 + x = 1

-29 + 8x / 8 = 1

-29 + 8x = 8

8x = 37

x = 37/8

so 37/8 must be added to -13/4 and -3/8 to get the result 1
