Hello. You forgot to show the calculations made by Nico and Lorena. The calculations are shown in the attached figure.
Answer:
Nico is correct because he knew -4/5 is equal to -4/5.
Explanation:
As you can see in the image below, Nico and Lorena had to solve the expression (2) x (1/6) x (-4/5).
In this case, the correct resolution is Noco's resolution, since it has the following resolution steps:
2x1x (-4) / 1x6x5 =
-8/30 =
-4/15
