Answer:
2.225
Step-by-step explanation:
2.5% converted to a decimal is 0.025
2.5% of 89 really means 2.5%*89 because in math, of means multiply.
89*0.025=2.225
You have to multiply by the decimal because the percent is a proportion in reality.
Think about it this way:
Since 2.5% of 89 is 2.225, 97.5% of 89 has to be 89-2.225, which is 86.775
and it is:
89*0.975=86.775
This is because the percentage is equal to 1 in whole.
0.025+0.975=1 or 2.5%+96.5%=100%
