Well, according to what you know, what do you think is the first step?

KittyGirl · Answer

ummmm I dont know to be honest

Eiwoh2 · Answer

Ok. So what we do here first is multiply -2/25 by 5 hours. What do you get?

KittyGirl · Answer

-0.4?

Eiwoh2 · Answer

Well, i forgot that you change "5" into "5/1" since "-2/25" is the other side. So try now, the same equation, but with 5/1.

KittyGirl · Answer

still -4.0?

KittyGirl · Answer

im pretty dumb when it comes to math

Eiwoh2 · Answer

Ok, so you usually get -10/25, and if you solve that, it turns into -2/5.
