Question 994681: Estimate the following percentages without using a calculator
0.99% of 83,583
20% of 5,008,340
0.52% of 472,028
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! The first one is 1% less than all of it.
If all is 83,583, 1% is two decimal places less, or 835.
Subtract that from 83,583 and you get 82718.
You probably can use 84,000-840 for this problem.
==============================
20% of anything is 1/5.
1.5 of 5 million is one million. That is a decent estimate.
==============================
The third one is about a half, and half of 472,028--use 470,000, and half of that is 235,000. This is an estimate, but it is a good one.
