Seems to be a typo:
If you meant to say just "an article" then it would be 1/3 of the article per minute.

Step-by-step explanation:
Answer z= 43/36
Step-by-step explanation:
We have given,
2 13/18 - z = 1 19/36
Since 2 13/18 = 49/18 and 1 19/36 = 55/36
So we can write,
2 13/18 - z = 1 19/36
or 49/18 - z = 55/36
or 49/18 - 55/36 = z
or (98 -55)/36 = z
or 43/36 = z
Hence we got z = 43/36
If the question you're asking is -13-(-12), then your answer would be -1. Hope that helped.
