I think it's this...
You have 6. I multiplied 3/5 by 6.
Giving me 3.6.
I took it from this one 3/5 of 60 = 36
so I did the same method and got the correct answer.
3/5 * 60 = 36.
I hope I helped. :)
Additive inverse means that the numbers that when added will equal to 0
so :
1.25 + x = 0
x = -1.25
meanwhile, multiplication inverse means if multiplied, the numbers will equal to 1
So :
1.25 x = 1
x = 1/1.25
x = 0.8
Hope this helps
