Estimate 48% of 52?

First, find the easy percentages (1%, 10%, and 50%)

50% is 1/2.

1/2 of 52 is 26. (1/2 of 50 is 25, and 1/2 of 2 is 1. 25+1=26)

10% is just moving the decimal place left one spot.

10% of 52.0 is 5.20

1% is just moving the decimal place left two spots.

1% of 52.0 is 0.520

Now, you can estimate 48% two ways. You can subtract 2% (2x1%) from 50%, or you can multiply 10% by 4 and add 8% (8x1%)

Since it'll be easier to subtract 2 than it will be to multiply by 4 and add 8, we'll subtract.

We'll round 0.52 to 0.5 to make it easier.

Multiplying 0.5 by 2 gives us 1.

26 (50% of 52) minus 1 = 25

48% of 52 is approximately 25.

48% is very close to 50% which is half of a number. Instead of finding 48% of 52, lets just find 50% of it.

52/2=26

As we were 2% over, let's subtract 1 to make it seem more accurate.

Your answer is 25
