Given:
A number is 400.
To find:
The additive inverse of 400.
Solution:
We know that the sum of a number and its additive inverse is 0.
If "a" is number and "b" is its additive inverse, then

Let x be the additive inverse of 400. Then,

Subtract both sides by 400.


Therefore, the additive inverse of 400 is
.
75% of 225 = 300.
10% = 30
20% = 60
30% = 90
40% = 120
50% = 150
60% = 180
70% = 210
80% = 240
90% = 270
